15F (1991AJ01)(See the Isobar Diagram for 15F) GENERAL: (See also (1986AJ01)) and 15.22 [Table of Energy Levels] (in PDF or PS) here. See (1989AYZU, 1989OG1B) and (1985AN28, 1986AN07, 1988CO15; theor.). See (1986AN07) for comments on 15Ne. Mass of 15FThe atomic mass excess of 15F is 16.77 ± 0.13 MeV. 15F is unstable with respect to breakup into 14O + p by 1.47 MeV: see (1981AJ01).
This reaction is not observed at E(3He) = 235 MeV, θlab = 20°: the differential cross section (c.m.) is ≤ 4 × 10-11 b (1984BI08).
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 [Γc.m. = 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 Γc.m. = 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 a differential cross section of 8 ± 4 nb/sr (1978KE06).
