29. 15N(3He, p)17O

Qm = 8.5537

Observed proton groups are displayed in Table 17.10 (in PDF or PS). See also (77AJ02). For the parameters of the first T = 3/2 state see Table 17.11 (in PDF or PS).

30. 15N(α, d)17O

Qm = -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.

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) x 10^-2 (MC77E). See also (LE76R; theor.).

33. 16O(n, n)16O

Eb = 4.1443

The scattering amplitude (bound) a = 5.805 ± 0.005 fm, σ_free = 3.761 ± 0.007 b (KO79W). 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) (FO73G, JO73, CI80, HI81A). (JO73) 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 (77AJ02)]: 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^- (JO73). T = 3/2 resonances are discussed by (HI81A): 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 (71AJ02) and in (77AJ02). At E_n = 23.5 keV, σ_t = 3.736 ± 0.007 b (BI75I; elemental O), σ_t has also been measured with high resolution for E_n = 4.5 to 8 MeV (CI80). At E_n = 40.3 and 50.4 MeV, σ_non is reported for elemntal O (ZA81). See also ¹⁶O, (FI75E, SU78E, LA79O, FR80K, LA80B, PA80E), (CI76, KI76K), (LI77I, JO79D; applications) and (LE76P, BA77OO, HO77C, TH77D, FE78C, LE78F, BA79DD; theor.).

Qm = -3.106

The angular distribution involving ¹⁷O_g.s. has been studied at E(⁷Li) = 36 MeV. The population of ¹⁷O*(0.87, 3.06, 3.84, 4.55, 5.38) is also reported (SC73M).

Qm = -4.032

See (KO81A).

46. 16O(14N, 13N)17O

Qm = -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 (MO76). An angular distribution involving ¹⁶O*(0 + 0.87) has also been reported at E(¹⁴N) = 155 MeV (NA76H). See also (IZ80A; theor.).

49. (a) 17O(γ, n)16O	Qm = -4.1443
(b) 17O(γ, 2n)15O	Qm = -19.808
(c) 17O(γ, α)13C	Qm = -6.3599

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 (JO79; 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 (JU80). For radiative widths see Table 17.13 (in PDF or PS). See also (77AJ02).

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 (KI78A). (MI79D) 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 (HY79). 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 (NO77B) 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 (NO77B). The transitions to ¹⁷O*(0.87, 5.08) can be described as single-particle transitions (KI78A). See also (HY80) and (AR78B, AR79N, ZA79, BO80B, LI81J; theor.).
