16F (1959AJ76)
(Not illustrated)
Mass of 16F: From the threshold of the 14N(3He, n)16F reaction and the Wapstra (1955WA1A) masses for 14N, 3He and n, the mass excess of 16F is 15.63 ± 0.02 MeV. A semi-empirical computation of the level shifts of the low T = 1 levels of 16N and 16O suggests that the ground state of 16F should have J = 0-, and be unstable to proton emission by about 1 MeV (1957EL1B). Using the (M - A) stated above, 16F is unstable with respect to proton emission by 0.81 MeV. The binding energies of a deuteron, a 3He-particle, and an α-particle in 16F are, respectively, 10.24, 9.37 and 8.98 MeV.
| 1. 14N(3He, n)16F | Qm = -1.18 |
A slow neutron threshold has been observed at E(3He) = 1.434 ± 0.015 MeV corresponding to the ground state of 16F (Q0 = -1.18 ± 0.01 MeV). There is some indication of another threshold corresponding to an excited state at ≈ 60 keV. The lifetime of 16F for decay into 15O + p is computed to be ≈ 10-19 sec (H. Bichsel, private communication). See also (1956BU22).
