Isobaric Analog Resonances in Proton Scattering from Te124, Te126, Te128, and Te130

Abstract

Isobaric analog states have been observed in proton elastic scattering from targets of ${}_{}{}^{124}{}_{}{}^{}\mathrm{Te}$, ${}_{}{}^{126}{}_{}{}^{}\mathrm{Te}$, ${}_{}{}^{128}{}_{}{}^{}\mathrm{Te}$, and ${}_{}{}^{130}{}_{}{}^{}\mathrm{Te}$. The levels thus observed in ${}_{}{}^{125}{}_{}{}^{}\mathrm{I}$, ${}_{}{}^{127}{}_{}{}^{}\mathrm{I}$, ${}_{}{}^{129}{}_{}{}^{}\mathrm{I}$, and ${}_{}{}^{131}{}_{}{}^{}\mathrm{I}$ are analogs of low-lying levels of ${}_{}{}^{125}{}_{}{}^{}\mathrm{Te}$, ${}_{}{}^{127}{}_{}{}^{}\mathrm{Te}$, ${}_{}{}^{129}{}_{}{}^{}\mathrm{Te}$, and ${}_{}{}^{131}{}_{}{}^{}\mathrm{Te}$. Resonance parameters, Coulomb displacement energies, and spectroscopic factors have been extracted. Results are compared with ($d,p$) studies on the target nuclei.
