Nuclear Structure Studies ofSr88andY89Using 19-MeV Proton Scattering and theSr88(He3, d)Reaction

摘要: Elastic and inelastic angular distributions were obtained for 19-MeV protons scattered from ${\mathrm{Sr}}^{88}$ ${\mathrm{Y}}^{89}$. Deuteron also the ${\mathrm{Sr}}^{88}({\mathrm{He}}^{3}, d)$ reaction used to study single-particle nature of excited states Spectroscopic information was by comparing proton with predictions distorted-wave theory using a real collective-model form factor. Proton low-lying ${\mathrm{Y}}^{89}$ compared determine if could be explained as weak coupling $2{p}_{\frac{1}{2}}$ core-excited ${\mathrm{Sr}}^{88}$. The at 1.49 1.74 MeV in do not appear described adequately states, while 2.22 (or 2.87) 2.52 do. those which terms simple shell-model configurations analyzed factors.
