Li-Induced Nucleon-Transfer Reactions between1p-Shell Nuclei: Isospin and Fractional-Parentage Studies

Abstract

Angular distributions for the one-nucleon transfer reactions ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$(${}_{}{}^6{}_{}{}^{}\mathrm{Li}$, ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$)${}_{}{}^{13}{}_{}{}^{}\mathrm{N}$ and ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$(${}_{}{}^6{}_{}{}^{}(\mathrm{L}\mathrm{i}$, ${}_{}{}^7{}_{}{}^{}\mathrm{Be}$)${}_{}{}^{13}{}_{}{}^{}\mathrm{C}$ were investigated at $E\left({}_{}{}^6{}_{}{}^{}\mathrm{Li}\right)=32\mathrm{}$ MeV and were compared with finite-range distorted wave calculations and theoretical spectroscopic factors. These one-nucleon transfer reactions induced by complex nuclei are described by the calculations just as well as those induced by light projectiles. A detailed study of the relative cross sections of the isobaric-spin analog transitions shows deviations from isospin symmetry that are due to Coulomb effects.
