A=15O (1976AJ04)

Mass of ¹⁵O: A re-determination of the mass of ¹⁵O has resulted from studies of the ¹⁴N(p, γ)¹⁵O (1972NE05) and ¹⁵N(p, n)¹⁵O (1972JE02, 1972SH08) reactions. Based on the (1971WA37) masses for n, p, ¹⁴N and ¹⁵N, the mass excesses are 2854.2 ± 1.1 keV (1972JE02), 2856.4 ± 0.9 keV (1972SH08) and 2855.9 ± 1.0 keV (1972NE05): the weighted mean of these three values is 2855.6 ± 0.6 keV (1972SH08) and we adopt it for ¹⁵O. The mass of ¹⁵O is then 15.0030656 (7) a.m.u., based on the conversion factor 931.502 (3) MeV/a.m.u.

1. ¹⁵O(β⁺)¹⁵N Q_m = 2.7538

Reported half-lives are listed in Table 15.19 (in PDF or PS) of (1970AJ04): the weighted mean is 122.24 ± 0.16 sec. See also (1972LE33). Using this value of τ_1/2 and Q_m, log f₀t = 3.636 [see (1972JE02)]. The K/β⁺ ratio is (10.7 ± 0.6) × 10^-4 (1972LE33). See also (1970DA21, 1970KO41, 1970ST04, 1972KO1A (also astrophys.), (1973MU1D, 1973WI04, 1973WI11, 1974LE1G, 1974WI1M, 1975BA59, 1975BL1G, 1975KR14; theor.).

2. ¹⁰B(⁶Li, n)¹⁵O Q_m = 15.213

See (1957NO17).

3. ¹⁰B(¹⁴N, ⁹Be)¹⁵O Q_m = 0.712

At E(¹⁴N) = 100 MeV, angular distributions have been measured to ¹⁵O*(0, 5.18 + 5.24, 6.79 + 6.86) (1975NA15). See also (1975KL1A).

4. ¹¹B(¹⁴N, ¹⁰Be)¹⁵O Q_m = -3.932

Elastic angular distributions have been studied at E(¹⁴N) = 41, 77 and 113 MeV (1971LI11). See also (1967PO13, 1973SC1J) and (1973DE35; theor.).

5. (a) ¹²C(³He, n)¹⁴O Q_m = -1.1486 E_b = 12.0761
(b) ¹²C(³He, p)¹⁴N Q_m = 4.7787
(c) ¹²C(³He, d)¹³N Q_m = -3.550
(d) ¹²C(³He, t)¹²N Q_m = -17.362
(e) ¹²C(³He, ³He)¹²C
(f) ¹²C(³He, α)¹¹C Q_m = 1.857
(g) ¹²C(³He, ⁷Li)⁸B Q_m = -22.899
(h) ¹²C(³He, ⁸Be)⁷Be Q_m = -5.780

Excitation functions for these reactions have been measured over a wide range of energies: see Table 15.20 (in PDF or PS) in (1970AJ04) and Table 15.20 (in PDF or PS) here. Observed resonances are displayed in Table 15.21 (in PDF or PS). For angular distributions see the writeups of the residual nuclei in (1974AJ01, 1975AJ02) and in ¹³N, ¹⁴N and ¹⁴O.

The yield of n₀ (reaction (a)) shows a resonance for E(³He) < 10 MeV [see, e.g., (1964OS01)] and little structure above, to 30.6 MeV (1970SI15). The yield of protons (to many final states in ¹⁴N) (reaction (b)) shows some clear resonances below E(³He) = 4.5 MeV and some uncorrelated structures [see Fig. 3 in (1973SO04) for a summary of the (1969HA49, 1973SO04) work for E(³He) = 4 to 12 MeV] at higher energies, with the possible exception of states at E_res = 7.8, 9.2 - 9.6 and (10.5) MeV (1973SO04). The reaction proceeds predominantly via the compound nucleus up to E(³He) = 12 MeV. The p₀, p₁ and p₂ yields show no appreciable structure for E(³He) = 16 to 30.6 MeV (1970SI15). See also (1973HE09), (1970VY1A; theor.) and the earlier references in (1970AJ04).

The activation cross section for ¹³N (reaction (c)) shows no structure for E(³He) = 6.5 to 30.6 MeV (1970SI15). A structure at E(³He) = 29.5 MeV is reported by (1970SI16: E(³He) = 22.3 to 30.6 MeV) in reaction (d). The elastic scattereing (reaction (e)) shows some resonant structure near 3, 5 and 6 MeV (see Table 15.21 (in PDF or PS)) and some largely uncorrelated structures in the range E(³He) = 16.5 to 24 MeV (1972MC01). There is some suggestion, however, of two resonances at E(³He) = 17 and 20 MeV (1972MC01). The 90° yield of reaction (d) to ¹²C*(15.1) [J^π = 1⁺; T = 1] shows a strong peak at 21.5 MeV, Γ ≈ 2.5 MeV (1970SI16). See also (1975WA1N; theor.).

The yield of α-particles has been measured at many energies to E(³He) = 18.6 MeV. Below E(³He) = 8 MeV resonances are observed^†: see Table 15.21 (in PDF or PS). Broad fluctuations are observed in the excitation functions for α₀, α₁ and α₃ for E(³He) = 12 to 18.6 MeV (1970GR08). For reaction (g) see (1971DE37: 37.7 to 41 MeV). For spallation reactions see (1975FU01, 1976WA1P).

6. ¹²C(α, n)¹⁵O Q_m = -8.5024

Angular distributions of the n₀ group have been measured at E_α = 18.4 to 23.1 MeV (1973CO04) and at 21.9 MeV (1975SK1B: also to some (unlisted) excited states). See also (1972DA32, 1974SH06) and (1970AJ04).

7. ¹²C(⁶Li, t)¹⁵O Q_m = -3.7185

States observed in this reaction are displayed in Table 15.22 (in PDF or PS) (1975BI06: E(⁶Li) = 59.8 MeV). Comparisons of angular distributions of the triton groups in this reaction and of the ³He groups to analog states in ¹⁵N have been made: analog correspondence is established for (10.48 - 10.80), (12.84 - 13.15 [u]) and (15.05 - 15.49 [u]) [E_x in ¹⁵O - E_x in ¹⁵N; u = unresolved]. Previous suggestions of analog pairs in ¹²C(¹⁰B, ⁷Li) and ¹²C(¹⁰B, ⁷Be) seem doubtful in view of this high resolution study which shows that some of the states involved in the previous comparisons were unresolved doublets (1975BI06). See also the work of (1970JO09, 1970JO1D: 12, 13, 14 MeV; t₀) and of (1971CH1R: 30.8 MeV; many states, comparisons with analogs). See also (1971LA1B, 1971BA2Q, 1972BA2B, 1974HO1P) and (1971BA2V, 1973OG1A).

8. ¹²C(¹⁰B, ⁷Li)¹⁵O Q_m = -5.712

At E(¹⁰B) = 100 MeV angular distributions have been measured for groups to ¹⁵O*(5.24, 7.28, 9.64, 10.47, 12.89, 15.36, 15.88, 17.13) and comparisons have been attempted with those for the reaction (¹⁰B, ⁷Be) to analog states in ¹⁵N [but see reaction above]. ¹⁵O*(12.89, 15.36) are very strongly populated (1973NA09). See also (1973BR1C, 1973SC1B).

9. ¹²C(¹¹B, ⁸Li)¹⁵O Q_m = -15.135

At E(¹¹B) = 114 MeV, θ_lab = 7° the spectrum is dominated by ¹⁵O*(12.84, 15.05). ¹⁵O*(7.28, 10.48) are also populated (1974AN36). See also (1975VO1H).

10. ¹²C(¹²C, ⁹Be)¹⁵O Q_m = -14.204

At E(¹²C) = 187 MeV, θ_lab = 8° the spectrum is dominated by ¹⁵O*(12.84, 15.05) [assumed J^π = 1/2^-, 13/2⁺, respectively]. ¹⁵O*(7.28) [J^π = 7/2⁺] is populated but ¹⁵O*(0, 6.79) are not observed (1974AN36, 1974SC1M). The situation is similar at E(¹²C) = 114 MeV but at E(¹²C) = 72 MeV (θ_lab = 11°) ¹⁵O*(0, 5.2, 7.28) are populated with comparable intensities (1974AN36). See also (1971SC1F, 1972SC21, 1973SC1J, 1973SC1B, 1973VO1E, 1975HA1P, 1975VO1H) and (1972BR21, 1975KU1L; theor.).

11. ¹²C(¹⁴N, ¹¹B)¹⁵O Q_m = -8.6597

See (1973SC1J).

12. ¹³C(³He, n)¹⁵O Q_m = 7.1297

Angular distributions of the n₀ group have previously been measured at E(³He) = 1.70 to 10.1 MeV: see (1970AJ04). Recent measurements of the distributions to most states of ¹⁵O with E_x < 10.5 MeV are displayed in Table 15.23 (in PDF or PS) (1971HI04, 1972ET01, 1972GE02: E(³He) = 5.5 - 6.2 MeV). At these energies it is necessary to combine direct interaction and compound nuclear calculations: these suggest that ¹⁵O*(5.18, 5.24, 7.28, 8.28(?)) have large 3p-4h strengths (1972GE02). See also (1973RH1A).

Branching ratio measurements by (1965WA16) are listed in Table 15.19 (in PDF or PS). The measured E_γ lead to E_x = 6180 ± 4, 6857 ± 3.2 and 7284 ± 7 keV (1965WA16).

13. ¹³C(¹¹B, ⁹Li)¹⁵O Q_m = -16.028

At E(¹¹B) = 114 MeV the states which are strongly populated are ¹⁵O*(5.24, 7.28, 11.2, 11.7) (1974AN36). See also (1973SC1J).

14. ¹⁴N(p, γ)¹⁵O Q_m = 7.2974

Observed resonances and states observed in the γ-decay are listed in Tables 15.24 (in PDF or PS) and 15.25 (in PDF or PS). Branching ratios are displayed in Table 15.19 (in PDF or PS): see (1970AJ04) and (1972KR14, 1972PH02, 1974KE02). See also (1971SH1D, 1972KU1J).

The cross section increases from (8.5 ± 3.7) × 10^-12 b at 100 keV to (140 ± 30) × 10^-12 b at 135 keV (1957LA13). Extrapolation from the E_p = 0.28 MeV resonance gives S(0) = 2.75 ± 0.50 keV · b, with zero slope to E_p = 0.05 MeV (1963HE11). For astrophysical implications see (1970AJ04, 1971BA1A, 1972CA1N, 1973CL1E, 1973TR1E).

(1972NE05) has measured accurately both the energy of the second resonance [1058.0 ± 0.5 keV] and the excitation energy of the corresponding state in ¹⁵O (E_x = 8284.1 ± 0.8 keV): this leads to a mass excess for ¹⁵O of 2855.9 ± 1.0 keV. For a comparison of this value and of two others which have led to a new mass of ¹⁵O see the "GENERAL" section here.

The 90° yield curve has been measured for E_p = 2.2 to 19.0 MeV: resonances are observed over most of the range in the γ₀ yield. The (γ₁ + γ₂) yield is relatively weak (1970KU09). For E_p = 18 to 28 MeV the excitation function for γ₀ decreases smoothly with energy: there is no evidence for structures (1975HA39). The (p, γ₀) reaction populates the T = 1/2 component of the giant dipole resonance: in ¹⁵N, ¹⁴C(p, γ₀) can populate both the T = 1/2 and the T = 3/2 components (1973PA1P). See also (1972SN1A, 1974MA1U), (1973HA1X, 1973SU1E) and (1970FR11; theor.).

15. (a) ¹⁴N(p, p)¹⁴N E_b = 7.2974
(b) ¹⁴N(p, 2p)¹³C Q_m = -7.5507

The yields of elastic and inelastic protons, and of γ-rays, have been studied at many energies: see (1959AJ76) and Table 15.25 (in PDF or PS) in (1970AJ04).

The scattering anomalies are superposed on a background which decreases less rapidly than the Rutherford cross section; for E_p < 2.3 MeV, the background is largely s-wave with some p-wave contribution above E_p = 1.5 MeV.

Observed resonances are displayed in Table 15.25 (in PDF or PS). The J^π assignments shown arise from considerations of branching ratios (see Table 15.19 (in PDF or PS)), measurements of angular distributions of γ-rays in the (p, γ) reaction, angular correlation studies and the work discussed in this section. See (1970AJ04) for the earlier references.

The recent work of (1969WE02, 1971LA23, 1972CH28, 1972PH02) has given us a much clearer picture of the resonances in this reaction below E_p = 6.2 MeV. These results, together with those obtained in the (p, γ) reaction, lead to a good understanding of the correspondence of the analog states in ¹⁵N and ¹⁵O below E_x ≈ 13 MeV: see (1972PH02) and Fig. 13 (Isobar Diagram).

Excitation functions have also been measured for the p₀, p₁ and p₂ groups for E_p = 17 to 26.5 MeV: there is no evidence for resonant behavior but the p₁ yield shows a large increase between E_p = 20 and 23 MeV (1972LU10). Total cross sections for the p₀ → p₉ groups have been measured at E_p = 8.6, 10.6, 12.6 and 14.6 MeV by (1973HA54). See also (1971ES1A, 1971OD01).

The polarization of the p₀ group has been measured at E_p = 49.4 MeV (1970CL10). The depolarization parameter, D, has been determined for the elastic transition at E_p = 16.15 MeV (1974CL1H). For other polarization measurements [E_p = 3.0 to 155 MeV] see Table 15.25 (in PDF or PS) in (1970AJ04). See also (1971ES1A).

16. ¹⁴N(p, n)¹⁴O Q_m = -5.9272 E_b = 7.2974

The excitation function has been measured for E_p = 6.3 to 12 MeV. Broad resonances are observed for E_p = 7.5 to 9.85 MeV: see Table 15.25 (in PDF or PS) (1964KU06). See also (1970AJ04), (1973CL1E; astrophys. questions) and (1970AL1J; theor.).

17. ¹⁴N(p, d)¹³N Q_m = -8.329 E_b = 7.2974

See ¹³N.

18. ¹⁴N(p, t)¹²N Q_m = -22.141 E_b = 7.2974

See ¹²N in (1975AJ02).

19. ¹⁴N(p, ³He)¹²C Q_m = -4.7787 E_b = 7.2974

Excitation functions for the ground state group have been measured at E_p = 7 to 11 MeV: some resonant structure is indicated (see Table 15.25 (in PDF or PS)) (1970ME30). Total cross section for the transitions to ¹²C*(0, 4.4) have been measured in the range E_p = 20.5 to 44.6 MeV (1974PI05). See also (1970AJ04) and ¹²C in (1975AJ02).

20. (a) ¹⁴N(p, α)¹¹C Q_m = -2.922 E_b = 7.2974
(b) ¹⁴N(p, 2α)⁷Be Q_m = -10.467

Excitation functions and total cross section measurements have been carried out for the α₀ group for E_p = 3.78 to 6.38 MeV (1976IN01), 5 to 22 MeV (1974JA11), 6 to 10.5 MeV (1968SH11; also α₁ in the range 8.2 - 10.5 MeV), 7 to 11 MeV (1970ME30; also α₁), 9 to 12 MeV (1974HU02) and 20 to 45 MeV (1974PI05; also α₁, α₂₊₃, α₄₊₅₊₆). Fairly sharp structures persist until E_p = 15 MeV (1974JA11): see Table 15.25 (in PDF or PS) for the parameters of observed resonances, and in particular footnote ^g. Reaction (b) whose cross section has been measured for E_p = 14 to 24 MeV displays a broad peak at ≈ 20 MeV (1974JA11). For astrophysical questions see (1974JA11, 1976IN01). See also (1975AJ02).

21. ¹⁴N(d, n)¹⁵O Q_m = 5.0728

Angular distribution studies have been carried out at many energies in the range E_d = 0.9 to 11.8 MeV: see Table 15.27 (in PDF or PS) in (1970AJ04) and (1970RI01: E_d = 2.80 - 5.35 MeV; E_x < 7.6 MeV), (1970BU15: 4.35, 5.5 MeV; n₀), (1972FO07: 5.2 MeV; pol. n to E_x < 7.6 MeV), (1971BO35: 5.6 and 6 MeV; E_x < 8.3 MeV) and (1971HI09: E_d-bar = 10.0, 11.8 MeV; n₀). See also (1970ME25, 1975HS01; theor.). The latter experiment shows that j_p in the ground state transition is predominantly 1/2. Information derived from DWBA analysis of the angular distributions, and from the very accurate γ-ray measurements of (1965WA16, 1966AL18, 1967CH19) are shown in Table 15.26 (in PDF or PS). See also (1973HI1C).

Neutron thresholds have been observed at E_d = 0.143 ± 0.004, 0.206 ± 0.005 (1963CS02), 1.24 ± 0.02, 1.967 ± 0.004 and 2.044 ± 0.004 MeV (1955MA85), corresponding to ¹⁵O*(5.198, 5.253, 6.16, 6.792, 6.859).

Gamma ray branching ratios are shown in Table 15.19 (in PDF or PS) (1965WA16, 1968GI11); lifetime measurements are listed in Table 15.18 (in PDF or PS). For polarization measurements see ¹⁶O in (1971AJ02) and (1977AJ02).

22. ¹⁴N(³He, d)¹⁵O Q_m = 1.8037

Angular distributions have been obtained at E(³He) = 11 MeV (1968BO14) and 14 MeV (1969AL04): see Table 15.26 (in PDF or PS). See also (1970AJ04) and (1971DZ07; theor.).

23. ¹⁴N(α, t)¹⁵O Q_m = -12.5172

Angular distributions of the t₀ group have been studied at E_α = 56 MeV (1969GA11). See also (1970AJ04).

24. ¹⁵N(p, n)¹⁵O Q_m = -3.5363
E_thresh = 3772.7 ± 1.1 keV (1972JE02);
E_thresh = 3775.1 ± 0.8 keV (1972SH08).

Angular distributions have been measured for the n₀ group at E_p = 3.95 to 18.5 MeV [and for the n₂ group at E_p = 5.5 MeV]: see (1970AJ04) for a listing of the references. See also (1971TH1D) and (1969HA1J, 1969SC1H; theor.). The threshold measurements listed above have led to a redetermination of the mass of ¹⁵O: see the "GENERAL" section here. See also ¹⁶O in (1977AJ02).

25. ¹⁵N(³He, t)¹⁵O Q_m = -2.7725

Angular distributions for the t₀, t₁₊₂, t₃, t₄₊₅, t₆ and t₇ groups have been studied in great detail for E(³He) = 16.5 to 37.7 MeV by (1975PI01) and 39.8 and 44.6 MeV (1969BA06: see Table 15.27 (in PDF or PS)). (1975PI01) report evidence that a tensor term is needed in the effective interaction and that all transitions show a similar decreasing trend with energy, while the cross sections for populating the analog states in ¹⁵N (in ¹⁵N(³He, ³He)) is increasing: this is consistent with DWBA with an energy-independent interaction (1975PI01). For other states of ¹⁵O observed in this reaction see Table 15.27 (in PDF or PS).

26. ¹⁶O(γ, n)¹⁵O Q_m = -15.6640

The spectrum of photoneutrons has been investigated at many energies. Meaurements over the giant dipole resonance region show the predominant strength is to the J^π = 1/2^- and 3/2^- states at E_x = 0 and 6.18 MeV, consistent with the basic validity of the single-particle, single-hole theory of photoexcitation in ¹⁶O. However, the positive parity states at E_x = 5.18, 5.24, 6.86 MeV are also populated suggesting some more complicated excitations in ¹⁶O: see (1970HO21) and the earlier references in (1970AJ04). The angular distributions of the ground state neutrons have been measured from threshold to E_γ = 28 MeV (1970JU02). See also (1969NA1D, 1970CO1G, 1971AD05, 1974SC23), (1970FI1D), (1969VA1A, 1970MU1D, 1973BA2H, 1973SP03, 1973WA1H; theor.) and ¹⁶O in (1977AJ02). For τ_m measurements see Table 15.18 (in PDF or PS) (1969MU07).

27. (a) ¹⁶O(p, d)¹⁵O Q_m = -13.4393
(b) ¹⁶O(p, pn)¹⁵O Q_m = -15.6640

Reaction (a) goes primarily to ¹⁵O*(0, 6.18). Angular distributions have been reported at many energies for E_p = 18.5 to 155.6 MeV: see Table 15.30 (in PDF or PS) in (1970AJ04) and (1975RO27: E_p = 65 MeV; d₀, d₃). See (1975RO27) for a review of spectroscopic factors. See also (1969SN1B, 1972KA1A, 1973FA10, 1975KA1A), (1972PA1A) and (1970DE38, 1970PR1A, 1971JO22, 1971MC15, 1972PR01, 1973BL04, 1973SA1A, 1973TA27; theor.). For reaction (b) see (1973GO27) and (1970AJ04).

28. ¹⁶O(d, t)¹⁵O Q_m = -9.4064

Angular distributions have been reported at E_d = 20 MeV (1969PU04; t₀ → t₃; l_n = 1, 0, 2, 1) and 28 MeV [(1968GA13; t₀), (1970IN1A, 1971IN1C; unpublished; t₀, t₁₊₂, t₃; also t₀ at E_d = 20 and 24 MeV)]. See (1970AJ04) for earlier references. At E_d = 28 MeV detailed comparison is made with the results from the mirror reaction ¹⁶O(d, ³He)¹⁵N (1968GA13). At E_d = 52 MeV the spectrum at θ_lab = 11° is dominated by ¹⁵O*(0, 6.18); ¹⁵O*(9.61, 10.48) are also populated (1973MA21). See also (1972PA1A), (1971BO50, 1974DA1D; theor.) and ¹⁸F in (1978AJ03).

29. ¹⁶O(³He, α)¹⁵O Q_m = 4.9145

The p_1/2 and p_3/2 hole states at E_x = 0 and 6.18 MeV are strongly populated in this reaction. Information on these and other states of ¹⁵O observed in this reaction is shown in Table 15.28 (in PDF or PS). Angular distributions have been measured at E(³He) = 5.2 to 36.6 MeV [see Table 15.32 (in PDF or PS) of (1970AJ04)], and more recently at E(³He) = 15 MeV (1974EL09), 16 MeV (1969DE06), 24 and 28 MeV (1973FU02) [see Table 15.28 (in PDF or PS)] and at 216 MeV (1974GE09; α₀, α₃). Branching ratios and multipole mixing ratios are displayed in Table 15.19 (in PDF or PS) (1965WA16, 1969KU01, 1971AV04). For lifetime measurements see Table 15.18 (in PDF or PS) (1965AL19).

¹⁵O*(7.28) has an excitation energy of 7274.2 ± 1.4 keV (1967HE1A) (which is 23.2 keV below the E_b of ¹⁴N + p) and J^π = 7/2⁺: thus it plays no significant role in determining that rate of the ¹⁴N(p, γ)¹⁵O reaction (1967HE1A). See also (1971BA1A). See also (1970CA28) and (1970LI1K, 1971MC15; theor.).

30. ¹⁶O(⁶Li, ⁷Li)¹⁵O Q_m = -8.413

At E(⁶Li) = 36 MeV angular distributions have been measured for the transitions ¹⁵O_g.s. + ⁷Li_g.s.,0.48 (1973SC26).

31. ¹⁶O(¹⁰B, ¹¹B)¹⁵O Q_m = -4.213

Angular distributions involving ¹⁵O(0) have been investigated at E(¹⁰B) = 100 MeV (1975NA15).

32. ¹⁶O(¹⁴N, ¹⁵N)¹⁵O Q_m = -4.8303

The ground state angular distribution has been studied at E(¹⁴N) = 155 MeV (1975NA15, 1975VO05). See also (1965GA1B).

33. ¹⁷O(p, t)¹⁵O Q_m = -11.324

At E_p = 39.8 MeV angular distributions of t₀ and t₃ groups have been compared to those of the ³He groups to the analog states in ¹⁵N (1970OL1B, 1971OL04).

34. ¹⁹F(³He, ⁷Li)¹⁵O Q_m = -4.319

Angular distributions are reported at E(³He) = 40.7 MeV invloving (¹⁵O_g.s. + ⁷Li*_g.s.,0.48), (¹⁵O*_5.19+5.24 + ⁷Li*_g.s.,0.48) and (¹⁵O*_6.18 + ⁷Li_g.s.) (1971DE04, 1971DE37): see also the analog reaction ¹⁹F(³He, ⁷Be)¹⁵N [reaction 88 in ¹⁵N].
