jDependence of Heavy-Ion—Induced Reactions

Abstract

The (${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$, ${}_{}{}^{15}{}_{}{}^{}\mathrm{N}$) and (${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$, ${}_{}{}^{11}{}_{}{}^{}\mathrm{B}$) reactions have been studied on targets of ${}_{}{}^{54}{}_{}{}^{}\mathrm{Fe}$, ${}_{}{}^{62}{}_{}{}^{}\mathrm{Ni}$, and ${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$ at incident ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ and ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ energies of 104 and 78 MeV, respectively. The two reactions are observed to populate states in the residual nuclei with different strengths, depending on the $j$ values of the final states. These results are believed to be a consequence of the selection rules for these reactions and suggest that spectroscopic assignments are possible with the use of heavy-ion reactions to complement other measurements.
