## 15F (1981AJ01)

(See the Isobar Diagram for 15F)

GENERAL: See also (1976AJ04) and Table 15.26 [Table of Energy Levels] (in PDF or PS) here.

General reviews and calculations:(1978GU10, 1979BE1H).

Mass of 15F:The atomis mass excess of 15F is 16.77 ± 0.13 MeV, based on the mean of the reported Q-values of the 20Ne(3He, 8Li)15F reaction. 15F is unstable with respect to breakup into 14O + p by 1.47 MeV.

 1. 20Ne(3He, 8Li)15F Qm = -29.83 Q0 = -29.73 ± 0.18 MeV (1978KE06); Q0 = -29.96 ± 0.2 MeV (1978BE26).

This reaction has been studied at E(3He) = 74.5 MeV (1978BE26) and 75.4 and 87.8 MeV (1978KE06). Two groups are observed: the ground state [Γcm = 0.8 ± 0.3 MeV (1978KE06). Two groups are observed: the ground state [Γcm = 0.8 ± 0.3 MeV (1978KE06), 1.2 ± 0.3 MeV (1978BE26)] and a relatively strongly populated state, presumed to be the mirror of 15C*(0.74) [Jπ = 5/2+], with Ex = 1.3 ± 0.1 MeV (1978KE06), 1.2 ± 0.2 MeV (1978BE26) and Γcm = 0.5 ± 0.2 MeV (1978KE06), 0.24 ± 0.03 MeV (1978BE26). The differential cross section for populating 15F*(1.3) is 250 ± 20 nb/sr at 10° and E(3He) = 74.5 MeV (1978BE26) and 80 ± 25 nb/sr at 9°, 87.8 MeV (1978KE06). At E(3He) = 75.4 MeV, θ = 9°, the ground state is populated with 8 ± 4 nb/sr (1978KE06).
