Single Particle Strengths from the (d,p) Reaction on $^{18}$F

ORAL

Abstract

The $^{19}$F nucleus has been studied extensively. However, there have previously been no direct measurements of $^{18}$F+n single-particle components in $^{19}$F, and no measure of neutron vacancies in the $^{18}$F ground state, as such experiments require a (radioactive) $^{18}$F target or beam. We have used the $^2$H($^{18}$F,p)$^{19}$F reaction to selectively populate such states in $^{19}$F. The 108.5-MeV radioactive $^{18}$F$^{+9}$ beam was provided by the HRIBF at ORNL. Proton-recoil coincidence data were taken for both $\alpha$-decaying and particle-stable final states. Angular distributions and spectroscopic factors were measured for eight proton groups, corresponding to 12 states in $^{19}$F. The results will be compared to model calculations. Results for states of astrophysical significance were reported earlier.$^1$ \\ \\ $^1$R. L. Kozub {\em et al.}, Phys. Rev. C \underline{71}, 032801 (R) (2005). \\ \\ Research supported by U. S.
