^{15}F (1981AJ01)(See the Isobar Diagram for ^{15}F) 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 ^{15}F:The atomis mass excess of ^{15}F is 16.77 ± 0.13 MeV, based on the mean of the reported Qvalues of the ^{20}Ne(^{3}He, ^{8}Li)^{15}F reaction. ^{15}F is unstable with respect to breakup into ^{14}O + p by 1.47 MeV.
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_{cm} = 0.8 ± 0.3 MeV (1978KE06). Two groups are observed: the ground state [Γ_{cm} = 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_{cm} = 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 8 ± 4 nb/sr (1978KE06).
