Obserevd neutron groups from reaction (a) and results from reaction (b)
are displayed in 16.31 (in PDF or PS). A recent measurement of
n-p angular correlations from 14N(3He,
n)16F(p)15O is reported in (1986RYZZ).
Measurements of pion spectra with polarized protons at Ep =
200 MeV are reported in (1987AZZY).
Levels in 16F at 0.39 (2-), 0.72 (3-),
5.40, 6.37 (4-), 7.85, and 11.52 MeV are observed.
Observed neutron groups are displayed in 16.31 (in PDF or PS). Angular distributions
of cross sections and/or polarization observables have been studied at
Ep = 35 - 135.2 MeV (1986AJ04) and recently
at Ep = 35 and 40 MeV (1987OH04)
and at Ep = 135 MeV (1989WAZZ).
See also (1983WA29).
For a comparison of (p, n) cross sections with B(M1) see (1986AJ04). A study of
Gamow-Teller strengths is described in (1988MA53).
An investigation of 0+ → 0- transitions is
discussed in (1986GA31).

and the reviews of (1986AN1E, 1986BA78).
Observed triton groups are shown in 16.31 (in PDF or PS). Angular distributions
at E(3He) = 81 MeV, analyzed by DWBA, and angular
correlation measurements [mainly involving protons to 15O*(0,
6.18)], together with information from reactions 1 and
4, lead to the Jπ
values shown in the table. The analog of the giant dipole resonance
[Ex ≈ 9.5 MeV] is strongly excited. The magnetic quadrupole
strength has two strong components in 16F*(0.42, 7.5). The
4- state at 6.4 MeV and the GDR have also been observed at
E(3He) = 170 MeV [see (1982AJ01, 1986AJ04)]. A recent
measurment of differential cross sections at E(3He) =
66 - 90 MeV and DWBA analysis is reported in (1989VA09).
