Low-Lying Sc44 Levels from the Sc45(p, d)Sc44 Reaction

Abstract

The level structure of ${\mathrm{Sc}}^{44}$ has been investigated by measuring the energy spectrum of deuterons from the ${\mathrm{Sc}}^{45}(p, d){\mathrm{Sc}}^{44}$ reaction at 17.5 MeV. The results show deuteron groups corresponding to 11 levels below 1.7 MeV at the following energies: 0, 0.266, 0.344, 0.646, 0.748, 0.952, 1.025, 1.165, 1.14, 1.51, and 1.66 MeV. The angular distributions of the deuterons have been obtained and show that the 6 lowest lying levels observed correspond to the pickup of an $f_{\frac{7}{2}}$ neutron from ${\mathrm{Sc}}^{45}$. A comparison is made of the present results with some recent theoretical predictions.
