^{15}F (1991AJ01)(See the Isobar Diagram for ^{15}F) 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 ^{15}Ne. Mass of ^{15}FThe atomic mass excess of ^{15}F is 16.77 ± 0.13 MeV. ^{15}F is unstable with respect to breakup into ^{14}O + p by 1.47 MeV: see (1981AJ01).
This reaction is not observed at E(^{3}He) = 235 MeV, θ_{lab} = 20°: the differential cross section (c.m.) is ≤ 4 × 10^{11} b (1984BI08).
This reaction has been studied at E(^{3}He) = 74.5 MeV (1978BE26) and 75.4 and 87.8 MeV (1978KE06). Two groups are observed: the ground state [Γ_{c.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 ^{15}C*(0.74) [J^{π} = 5/2^{+}], with E_{x} = 1.3 ± 0.1 MeV (1978KE06), 1.2 ± 0.2 MeV (1978BE26) and Γ_{c.m.} = 0.5 ± 0.2 MeV (1978KE06), 0.24 ± 0.03 MeV (1978BE26). The differential cross section for populating ^{15}F*(1.3) is 250 ± 20 nb/sr at 10° and E(^{3}He) = 74.5 MeV (1978BE26) and 80 ± 25 nb/sr at 9°, 87.8 MeV (1978KE06). At E(^{3}He) = 75.4 MeV, θ = 9°, the ground state is populated with a differential cross section of 8 ± 4 nb/sr (1978KE06).
