Study of the ReactionsO16(Li6,He3)F19andO16(Li6,t)Ne19atE(Li6)=24MeV

Abstract

At a bombarding energy of 24 MeV, angular distributions have been measured for the reactions ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ (${}_{}{}^6{}_{}{}^{}\mathrm{Li}$, ${}_{}{}^3{}_{}{}^{}\mathrm{He}$) ${}_{}{}^{19}{}_{}{}^{}\mathrm{F}$ and ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}({}_{}{}^6{}_{}{}^{}\mathrm{Li},t){}_{}{}^{19}{}_{}{}^{}\mathrm{Ne}$. A distorted-wave Born-approximation (DWBA) analysis in the zero-range three-nucleon-cluster-transfer approximation has been performed. The sensitivity of the DWBA calculations on ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ parameters was demonstrated, with 160-190-MeV real-well-depth ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ parameters giving the best fits. By using Watson's ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ parameters, it was possible to account for the observed differences between the (${}_{}{}^6{}_{}{}^{}\mathrm{Li}$, ${}_{}{}^3{}_{}{}^{}\mathrm{He}$) and (${}_{}{}^6{}_{}{}^{}\mathrm{Li},t$) cross sections. The extracted relative spectroscopic strengths are consistent with the known structure of the final states.
