GENERAL: See (1978AJ03) and Table 19.1 [Table of Energy Levels] (in PDF or PS).

Shell model: (1977GR16, 1979DA15, 1980KU05, 1982KI02).

Electromagnetic transitions: (1976MC1G, 1978KR19, 1980KU05).

Special states: (1977GR16, 1977SH18, 1979DA15, 1982KI02).

Astrophysical questions: (1979WO07).

Complex reactions involving ¹⁹O: (1978KO01, 1979AL22, 1981GR08).

Other topics: (1977GR16, 1977SH18, 1979BE1H, 1979CO09, 1980SH1H, 1982KI02).

Ground-state properties of ¹⁹O: (1976MC1G).

1. 19O(β-)19F

Qm = 4.819

The weighted mean of several reported half-lives is 26.91 ± 0.08 sec: see (1972AJ02). The decay is complex: see ¹⁹F, reaction 36 and Table 19.20 (in PDF or PS). See also (1977OK1A; theor.).

2. 9Be(18O, 8Be)19O

Qm = 2.292

Cross sections and S-factors are reported for E_cm = 1.77 to 6.71 MeV (1980RO13). See also (1978AJ03).

3. 13C(7Li, p)19O

Qm = 7.413

States of ¹⁹O reported in this reaction are displayed in Table 19.3 (in PDF or PS) (1977FO10).

4. 17O(t, p)19O

Qm = 3.520

Proton groups corresponding to ¹⁹O states with E_x < 5.6 MeV and E_γ measurements are displayed in Table 19.4 (in PDF or PS).

5. 18O(n, γ)19O

Qm = 3.957

The thermal capture cross section is 0.16 ± 0.01 mb (1981MUZQ). See also (1978AJ03).

6. 18O(n, n)18O

Eb = 3.957

The scattering amplitude (bound) a = 5.84 ± 0.07 fm, σ_free = 3.86 ± 0.10 b (1979KO26). The total cross section measured for E_n = 0.14 to 2.47 MeV shows five resonances at E_n = 0.66, 1.19, 1.26, 1.84 and 2.45 MeV [see Table 19.5 (in PDF or PS)] in addition to a broad maximum at E_n = 1.6 MeV and resonance structure near 2.3 MeV (1965VA03). A phase-shift analysis by (1964DO08, 1973DO05) is consistent with the (1965VA03) results and suggests that the two broad structures can each be accounted for in terms of two levels whose parameters are displayed in Table 19.5 (in PDF or PS). At higher energies [E_n = 2.45 to 8.50 MeV and 10.6 to 19.0 MeV] the total cross section shows additional structures. See also (1978AJ03, 1981MUZQ).

7. (a) 18O(n, p)18N	Qm = -13.25	Eb = 3.957
(b) 18O(n, d)17N	Qm = -13.717

See (1978AJ03).

8. (a) 18O(n, α)15C	Qm = -5.0097	Eb = 3.957
(b) 18O(n, d)17N	Qm = -13.717

The total cross sections for the α₀ and α₁ groups have been measured for E_n = 7.5 to 8.6 MeV: resonance structure is reported at E_n = 7.70 ± 0.05 and 8.05 ± 0.05 MeV with Γ_lab = 0.25 and 0.35 MeV, respectively [¹⁹O*(11.25, 11.58)] (1967ST28).

9. 18O(d, p)19O

Qm = 1.732

Angular distributions have been measured at E_d = 0.8 to 15 MeV: see (1978AJ03) for the earlier work and (1979ST21; E_d-bar = 8 to 12 MeV). The l_n values and spectroscopic factors dereived from these measurements are displayed in Table 19.4 (in PDF or PS).

Branching ratios are shown in Table 19.3 (in PDF or PS). ¹⁹O*(0.096) has g = -0.48 ± 0.06; its configuration appears to be mainly d³_5/2 and B(M1) = (0.040 ± 0.015) μ²_N (1976GO09). The ΔE value for the 1.47 → 0.096 transition is 1375.3 ± 0.5 keV. Assuming E_x = 96.0 ± 0.5 keV (Table 19.1 (in PDF or PS)) E_x = 1471.4 ± 0.7 keV (1973WA10). Angular correlations are consistent with J^π = 5/2⁺ for the ground state and unambiguously fix J^π = 3/2⁺ and 1/2⁺, respectively, for ¹⁹O*(0.096, 1.47) (1965AL13).

10. (a) 18O(13C, 12C)19O	Qm = -0.989
(b) 18O(14C, 13C)19O	Qm = -4.219
(c) 18O(17O, 16O)19O	Qm = -0.186
(d) 18O(18O, 17O)19O	Qm = -4.087

An angular distribution is reported for reaction (a) at E(¹⁸O) = 31 MeV to ¹⁹O_g.s+0.096 (1978CH16). At E(¹⁸O) = 36 MeV angular distributions for reaction (c) to ¹⁹O*(0 + 0.096, 1.47) have been studied by (1977KA1Y). Differential cross sections are reported for E(¹⁸O) = 30 to 36 MeV for reaction (d) (1977KA21). See also (1978AJ03).

11. 19N(β-)19O

Qm = 12.54

The β-decay of ¹⁹N has not been observed.

12. 19F(n, p)19O

Qm = -4.036

Angular distributions have been reported at E_n = 14.1 and 14.4 MeV for the p₀ → p₂ groups: see (1972AJ02) and ²⁰F.
