Identification of analog pairs inC13andN13by means of theB10(Li6,He3)C13andB10(Li6,t)N13reactions

Abstract

The ${}_{}{}^{10}{}_{}{}^{}\mathrm{B}({}_{}{}^6{}_{}{}^{}\mathrm{Li},t){}_{}{}^{13}{}_{}{}^{}\mathrm{N}$ and ${}_{}{}^{10}{}_{}{}^{}\mathrm{B}({}_{}{}^6{}_{}{}^{}\mathrm{Li},{}_{}{}^3{}_{}{}^{}\mathrm{He}){}_{}{}^{13}{}_{}{}^{}\mathrm{C}$ reactions were induced with $E_{{}_{}{}^6{}_{}{}^{}\mathrm{Li}}=18\mathrm{}$ MeV in order to test the assignment of mirror pairs by direct comparison of the resulting spectra. The technique appears to be reliable up to excitations of ∼ 10 MeV for these cases. Some new analog pairs are suggested, and a hitherto unreported state is identified at 9.00 MeV in ${}_{}{}^{13}{}_{}{}^{}\mathrm{N}$.
