(b) ¹³C(α, (α)¹³C

The yield of neutrons increases monotonically for E_α = 0.475 to 1 MeV: S(E) = [(5.48 ± 1.77) + (12.05 ± 3.91)E] × 10⁵ MeV · b (1968DA05; E_α = 0.48 to 0.70 MeV), [(4.87 ± 1.28) + (10.86 ± 2.46)E] × 10⁵ MeV · b (1976RA36, 1977RA1C; E_α = 0.60 to 0.90 MeV). Astrophysical considerations are discussed by (1976RA36, 1977CO1U, 1977RA1C) and see (1977AJ02). Yield curves for reaction (a) have been measured for E_α = 1.0 to 22.5 MeV: see (1971AJ02, 1977AJ02) and (1975BE44; αγ_6.13; thresh. to 7.2 MeV).

12. ¹³C(⁶Li, d)¹⁷O Q_m = 4.886

Angular distributions of deuteron groups to many states of ¹⁷O have been measured earlier at E(⁶Li) = 18 and 25.6 MeV: see Table 17.7 (in PDF or PS) in (1977AJ02). At E(⁶Li) = 35.5 MeV angular distributions are reported to ¹⁷O*(13.58 ± 0.02) which is strongly populated. Comparisons with ¹²C(⁶Li, d)¹⁶O*(16.29) and with the results of reaction 13 here suggest that the peak corresponding to ¹⁷O*(13.58) contains a state or states of spin 11/2^-, 13/2^-, or both, based on ¹⁶O*(16.29) (1978CL08). (d, α) angular correlations [E(⁶Li) = 26, 29 and 34 MeV] indicate the involvement of ¹⁷O states at 13.6 ± 0.1 [l = 6], 14.15 ± 0.1 [5], 15.1 ± 0.1 [5], 15.95 ± 0.15 [5], 16.6 ± 0.15 [6], 17.1 ± 0.15 [6], 19.6 ± 0.15 [7], 20.2 ± 0.15 [7], 21.2 [7] and 22.1 MeV. Γ ≈ 0.1, 0.5, 0.7, 0.25 and 0.25 MeV for ¹⁷O*(14.2, 15.1, 16.0, 19.6, 20.2) (1978AR15). See also (1976ST22; theor.).

13. ¹³C(⁷Li, t)¹⁷O Q_m = 3.893

Angular distributions of triton groups to many states of ¹⁷O have been measured earlier at E(⁷Li) = 17, 20.5 and 30.1 MeV: see Table 17.7 (in PDF or PS) in (1977AJ02). At E(⁷Li) = 35.7 MeV angular distributions are reported to ¹⁷O*(3.06) and to ¹⁷O*(13.58) which is preferentially populated (see discusion in reaction 12). Narrow states at E_x = 14.86, 18.17 and 19.24 MeV are also strongly excited (1978CL08). See also (1978MA2G).

14. ¹³C(¹³C, ⁹Be)¹⁷O Q_m = -4.288

At E(¹³C) = 105 MeV states of ¹⁷O with E_x = 3.9, 5.2, 5.8 ± 0.1, 7.2, 7.6, 8.4 ± 0.06, 8.9, 9.8 ± 0.07, 10.55 ± 0.06, 12.1 ± 0.06, 13.3, 14.6 and 18.9 ± 0.14 MeV are reported (1979BR04).

15. (a) ¹³C(¹⁶O, ¹²C)¹⁷O Q_m = -0.8021

Angular distributions for reaction (a) have been studied at E(¹⁶O) = 12 to 25 MeV [¹⁷O*(0, 0.87): see (1977AJ02)] and at 13 and 14 MeV (1976DU04; see also for r_n). For reaction (b) see (1978CH16). See also (1980GO1L, 1980PA04; theor.).

16. ¹⁴C(³He, γ)¹⁷O Q_m = 18.7611

The capture cross sections at 90° for γ₀ and for γ₁ have been studied for E(³He) = 3.2 to 7.5 MeV and angular distributions of the γ-rays have been studied at the six observed resonances: see Table 17.9 (in PDF or PS) (1976CH04).

17. (a) ¹⁴C(³He, n)¹⁶O Q_m = 14.6168 E_b = 18.7611

18. ¹⁴C(α, n)¹⁷O Q_m = -1.8167

The upper limits to the decays 3.06 → 0 and 3.84 → 0.87 are, respectively, 2 and 5%. A study of n-γ correlations leads to J^π = 1/2^- and (5/2^-) for ¹⁷O*(3.06, 3.84) (1964AL11).

19. ¹⁴C(¹⁶O, ¹³C)¹⁷O Q_m = -4.0322

Angular distributions have been measured at E(¹⁶O) = 20, 25 and 30 MeV (¹⁷O*(0, 0.87)): see (1977AJ02). See also (1977WE1H; theor.).

20. (a) ¹⁴N(t, γ)¹⁷O Q_m = 18.6233

(d) ¹⁴N(t, t)¹⁴N
(e) ¹⁴N(t, α)¹³C Q_m = 12.2634

The excitation functions for γ₀ and γ₁ have been measured for E_t = 0.8 to 3.3 MeV: broad resonances are observed at 2.2 and 2.8 MeV in the γ₀ cross section, and at 2.4 and 2.8 MeV in the γ₁ cross section. Both also exhibit a structure at 1.5 MeV. The data are consistent with states at E_x = 19.76 ± 0.06 [J^π = 3/2], 20.39 ± 0.05 [5/2, 7/2^-], 20.58 ± 0.05 [1/2] and 21.05 ± 0.05 MeV [3/2] with Γ = 0.55 ± 0.05, 0.66 ± 0.07, 0.57 ± 0.08 and 0.47 ± 0.06 MeV, and possibly with a state at ≈ 19.3 MeV. Γ_γ₀ > 1.0, 4.3 and 5.8 eV for ¹⁷O*(19.8, 20.4, 21.1) and Γ_γ₁ > 2.3, 5.1 and 6.5 eV for ¹⁷O*(19.8, 20.6, 21.1) (1980LO07). For reactions (b) → (e) see (1977AJ02). See also ¹⁶N here, and ¹³C, ¹⁴N and ¹⁵N in (1981AJ01).

21. (a) ¹⁴N(α, p)¹⁷O Q_m = -1.1908
(b) ¹⁴N(α, αp)¹³C Q_m = -7.55063

Angular distributions have been measured for ¹⁷O states with E_x < 7.6 MeV in the range E_α = 8.1 → 33.3 MeV: see a listing of the references in (1971AJ02). The sequential decay [reaction (b)] appears to take place via ¹⁷O states with 8.46 ≤ E_x ≤ 13.57 MeV. Those involved are believed to have J ≥ 5/2, Γ_α/Γ ≥ 0.6 (1969BA17).

22. ¹⁴N(⁶Li, ³He)¹⁷O Q_m = 2.829

At E(⁶Li) = 18 MeV, the groups in this reaction and the triton groups in the mirror reaction (see reaction 8 in ¹⁷F) have been compared: ¹⁷O*(3.84, 4.55, 5.22, 5.70 + 5.73) are strongly excited. ¹⁷O*(0, 0.87, 3.06, 5.09, 5.38, 5.87 + 5.94, 6.86, 6.97) are also populated (1973BI01). See also (1977MA2G, 1978MA2G).

23. ¹⁴N(¹⁰B, ⁷Be)¹⁷O Q_m = -0.045

See (1977MO1A).

24. ¹⁵N(d, γ)¹⁷O Q_m = 14.0473

See (1977AJ02) [paper quoted there has not been published].

25. ¹⁵N(d, n)¹⁶O Q_m = 9.9029 E_b = 14.0473

Excitation functions have been measured for a number of neutron groups for E_d = 0.5 to 5.9 MeV: a great deal of unresolved structure is apparent. Polarization measurements are reported for E_d = 1.6 to 5.5 MeV and at 10.0 and 11.8 MeV. See (1977AJ02) for a listing of the work. See also ¹⁶O.

26. ¹⁵N(d, p)¹⁶N Q_m = 0.267 E_b = 14.0473

Excitation functions have been obtained for E_d = 0.3 to 6.3 MeV: [see (1977AJ02)] and at E_d = 1.4 to 2.7 MeV (1977CA03; p₀ → p₃). Structures are reported at E_d = 1.8 [p₀, p₁, p₃] and 2.4 MeV [p₂] [¹⁷O*(15.6, 16.2)] (1977CA03).

27. ¹⁵N(d, d)¹⁵N E_b = 14.0473

Excitation functions for d₀ have been measured for E_d = 4.25 to 6.25 MeV [see (1977AJ02)] and 1.4 to 2.7 MeV (1977CA03). The latter report structures at ≈ 1.4 and 1.8 MeV.

28. ¹⁵N(d, α)¹³C Q_m = 7.6874 E_b = 14.0473

Yield curves have been measured for E_d = 0.8 to 2.5 MeV [see (1977AJ02)] and 1.2 to 2.7 MeV (1976CA28; α₀ → α₃): structures have been reported at E_d = 1.06 and 1.25 MeV, and at ≈ 1.8 MeV. The latter has Γ ≈ 300 keV (1976CA28).

29. ¹⁵N(³He, p)¹⁷O Q_m = 8.5537

Observed proton groups are displayed in Table 17.10 (in PDF or PS). See also (1977AJ02). For the parameters of the first T = 3/2 state see Table 17.11 (in PDF or PS).

30. ¹⁵N(α, d)¹⁷O Q_m = -9.7995

At E_α = 45.4 MeV, the deuteron spectrum is dominated by the groups corresponding to states with E_x = 7.742 ± 0.020 and 9.137 ± 0.030 MeV. These states are assigned J^π = (11/2^-) and (9/2^-) and arise from a dominant (d_5/2)²₅p^-1_1/2 configuration. Angular distributions were measured as well for the deuterons corresponding to ¹⁷O_g.s. and to states with E_x = 0.87 ± 0.05, 5.22, 5.70, 7.38, 8.46, 8.89 and 9.81 [± 0.03] MeV. In addition the population of ¹⁷O*(3.84, 4.55, 8.15 ± 0.03) is also reported (1969LU07).

31. ¹⁵N(¹¹B, ⁹Be)¹⁷O Q_m = -1.769

At E(¹¹B) = 115 MeV angular distributions have been studied to ¹⁷O*(5.23, 7.75, 9.18) [J^π = 9/2^-, 11/2^-, 9/2^-] (1979RA10, 1980PR09). See also (1977AJ02).

32. ¹⁶O(n, γ)¹⁷O Q_m = 4.1443
σ_capt. = 202 ± 28 μb (1977MC05).

At thermal energies the branchings via ¹⁷O*(0.87, 3.05) are (18 ± 3) and (82 ± 3)%; E_αγ = 870.89 ± 0.22 keV. The cross section for two-photon emission σ₂γ < 3 ± 19μb for 1200 < E_αγ < 2843 keV. The two-photon branching ratio is (1.6 ± 10) × 10^-2 (1977MC05). See also (1976LE27; theor.).

33. ¹⁶O(n, n)¹⁶O E_b = 4.1443

The scattering amplitude (bound) a = 5.805 ± 0.005 fm, σ_free = 3.761 ± 0.007 b (1979KO26). High resolution cross-section measurements and analyses of the elastic scattering and of the (n, α) and ¹³C(α, n) data have led to a much better understanding of the ¹⁷O structure below E_x = 18.2 MeV: see Table 17.12 (in PDF or PS) (1973FO11, 1973JO01, 1980CI03, 1981HI01). (1973JO01) has performed a multi-level two-channel R-matrix analysis. Five states contain nearly 100% of the 1d_3/2 strength and have their eigenenergy at E_x ≈ 5.7 MeV [the dominant state is ¹⁷O*(5.08)]. Spectroscopic factors are deduced for 26 states in ¹⁷O for 4.5 < E_x < 9.5 MeV [see Table 17.12 (in PDF or PS) in (1977AJ02)]: the sum of these factors is 1% for J^π = 1/2⁺, 5% for 1/2^-, 12% for 3/2^-, 99% for 3/2⁺m 0.1% for 5/2⁺, 1% for 5/2^- and 14% for 7/2^- (1973JO01). T = 3/2 resonances are discussed by (1981HI01): see Tables 17.11 (in PDF or PS) and 17.12 (in PDF or PS).

Cross-section measurements are listed in Table 17.10 (in PDF or PS) of (1971AJ02) and in (1977AJ02). At E_n = 23.5 keV, σ_t = 3.736 ± 0.007 b (1975BI14; elemental O), σ_t has also been measured with high resolution for E_n = 4.5 to 8 MeV (1980CI03). At E_n = 40.3 and 50.4 MeV, σ_non is reported for elemntal O (1981ZA03). See also ¹⁶O, (1975FI1B, 1978SU1E, 1979LAZQ, 1980FR1K, 1980LA1D, 1980PA10), (1976CI1A, 1976KI1F), (1977LI1N, 1979JO1H; applications) and (1976LE26, 1977BA1N, 1977HO1P, 1977TH09, 1978FE06, 1978LE1H, 1979BA29; theor.).

34. ¹⁶O(n, n')¹⁶O* E_b = 4.1443

46. ¹⁶O(¹⁴N, ¹³N)¹⁷O Q_m = -6.409

At E(¹⁴N) = 79 MeV angular distributions involving ¹⁷O*(0, 0.87) have been studied: an anomaly is observed in the phase behavior of the distribution to the excited state. From this and other studies it is concluded that a multistep process via inelastic scattering is unlikely to occur in the excitation of 2s_1/2 states (1976MO03). An angular distribution involving ¹⁷O*(0 + 0.87) has also been reported at E(¹⁴N) = 155 MeV (1975NA15). See also (1980IZ1B; theor.).

Forty-five resonances are reported for E_x up to 26.9 MeV in the differential cross section for (γ, n₀). T = 1/2 components of the giant resonance are observed at E_x = 19.8, 21.5 and ≈ 26 MeV (1979JO05; brems.). Monoenergetic photons with E_αγ = 8.5 to 39.7 MeV have been used to measure the (γ, n) and the (γ, 2n) [above 10 MeV] cross sections. The giant dipole resonance, 6 MeV broad, is centered at 23 MeV; a pigmy resonance is also observed at 13 MeV. Most of the GDR strength decays to T = 1 states in ¹⁶O: this implies a T = 3/2 assignment for the main part of the GDR. A broad structure, of T = 1/2 nature, with 28 < E_x < 36 MeV is also reported (1980JU01). For radiative widths see Table 17.13 (in PDF or PS). See also (1977AJ02).

50. ¹⁷O(e, e)¹⁷O

The ¹⁷O charge radius, < r² >^1/2 = 2.710 ± 0.015 fm, based on < r²₁₇ >^1/2/ < r²₁₆ >^1/2 = 1.0015 ± 0.0025 (1978KI01). (1979MI09) report < r²₁₇ >^1/2 - < r²₁₆ >^1/2 = -0.008 ± 0.007 fm. Considerable deviation from single-particle predictions is observed in the elastic scattering for an effective momentum transfer range of 0.55 to 2.8 fm^-1 (1979HY01). Inelastic scattering is reported to a number of ¹⁷O states: see Tables 17.14 (in PDF or PS) and 17.15 (in PDF or PS). The data of (1977NO06) show a broad dipole resonance centered at 22 - 23 MeV with strength extending down to 10 - 12 MeV. A smaller resonance, with a form factor consistent with C2, is found between E_x = 17.5 and 19.6 MeV (1977NO06). The transitions to ¹⁷O*(0.87, 5.08) can be described as single-particle transitions (1978KI01). See also (1980HY1A) and (1978AR04, 1979AR1F, 1979ZA1C, 1980BO04, 1981LI1N; theor.).
