Levels ofSc44from theSc45(d,t)Sc44Reaction

Abstract

Energy levels in ${\mathrm{Sc}}^{44}$ have been studied using the ${\mathrm{Sc}}^{45}\mathrm{}(d,t)\mathrm{}{\mathrm{Sc}}^{44}$ reaction at 19.5-MeV incident energy. Thirty-six levels in ${\mathrm{Sc}}^{44}$ below an excitation energy of 3.2 MeV were observed. Angular distributions were measured, and compared with the distorted-wave Born-approximation theory to obtain transferred $l$ values and spectroscopic factors. A considerable amount of $l=1\mathrm{}$ strength was found, indicating the presence of $2p$ neutrons in the ground state of ${\mathrm{Sc}}^{45}$. A recent shell-model calculation using an ${\left(f_{\frac{7}{2}}\right)}^4$ configuration shows qualitative agreement with experiment.
