(He3, d) Reaction on Ca42 and Ca44

Abstract

Energy levels in ${\mathrm{Sc}}^{43}$ and ${\mathrm{Sc}}^{45}$ have been studied using the ${\mathrm{Ca}}^{42,44}({\mathrm{He}}^3, d){\mathrm{Sc}}^{43,45}$ reactions at 10 and 11 MeV. Twenty-nine levels in ${\mathrm{Sc}}^{43}$ and seventy-four levels in ${\mathrm{Sc}}^{45}$ were observed below an excitation energy of 6.3 MeV. Angular distributions of the reaction deuterons were measured out to a laboratory angle of 50°. The angular distributions of the more intense groups have been compared with the predictions of a distorted-wave Born-approximation calculation, and angular momentum transfers of $l=0\mathrm{}$, $l=1\mathrm{}$, $l=2\mathrm{}$, and $l=3\mathrm{}$ have been identified. Most of the available $1f_{\frac{7}{2}}$ and $2p$ single-particle transition strength has been observed.
