Spectroscopic Factors forT=32States inA=19Nuclei

Abstract

Distorted-wave calculations have been performed for the reaction ${}_{}{}^{18}{}_{}{}^{}\mathrm{O}\mathrm{}(d,p)\mathrm{}{}_{}{}^{19}{}_{}{}^{}\mathrm{O}$ to the ${\frac{5}{2}}^{+}$ ground state and the ${\mathrm{½}}^{+}$ state at 1.467 MeV in ${}_{}{}^{19}{}_{}{}^{}\mathrm{O}$, as well as for the reaction ${}_{}{}^{18}{}_{}{}^{}\mathrm{O}({}_{}{}^3{}_{}{}^{}\mathrm{He},d){}_{}{}^{19}{}_{}{}^{}\mathrm{F}$ leading to the analogs of these states — the (bound) ${\frac{5}{2}}^{+}$ state at 7.540 MeV and the (unbound) ${\mathrm{½}}^{+}$ state at 8.795 MeV in ${}_{}{}^{19}{}_{}{}^{}\mathrm{F}$. The resulting spectroscopic factors are in good agreement with each other, although previous work had suggested a discrepancy. However, the spectroscopic factors are only about half as large as the shell-model predictions.
