Abstract
The 19F nucleus has been studied extensively. However, there have been no comprehensive experimental studies
of 18F+n single-particle components in 19F, and no measure of neutron vacancies in the 18F ground state, as such
experiments require a (radioactive) 18F target or beam. We have used the 2H(18F,p)19F reaction to selectively
populate states in 19F that are of 18F+n character. The 108.5-MeV radioactive 18F+9 beam was provided by the
Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory. Proton-recoil coincidence data were
taken for both �-decaying and particle-stable final states. Angular distributions and spectroscopic factors were
measured for nine proton groups, corresponding to 13 states in 19F. The results are compared to shell model
calculations.
