Stripping Analysis of theSc45(d,p)Sc46Reaction

Abstract

The ${\mathrm{Sc}}^{45}(d,p){\mathrm{Sc}}^{46}$ reaction has been studied with a multiple-gap magnetic spectrograph and the MIT-ONR electrostatic accelerator. Eighty-four energy levels were observed, and angular distributions of the corresponding proton groups were analyzed up to an excitation energy of 4.0 MeV. Eighty-five additional energy levels in ${\mathrm{Sc}}^{46}$ were observed between 4.0 and 6.0 MeV where the level density is seen to increase rapidly with excitation energy. Some unresolved particle groups are estimated to have separations of a few keV. The ground-state $Q$ value was measured to be 6.541\ifmmode\pm\else\textpm\fi{}0.008 MeV. The angular distributions were measured in 7.5-deg intervals between 7.5 and 172.5 deg. The assignments of the captured-neutron angular-momentum ${l}_{n}$ were based on the position of the first maximum as predicted by a distorted-wave Born-approximation theoretical calculation. The transition strengths for the groups, for which ${l}_{n}$ assignments were made, were determined from the measured differential cross sections and the predictions of the distorted-wave, deuteron-stripping analysis.
