Ca48(d, n)Sc49reaction atEd=20MeV; proton single-particle states inSc49

Abstract

The $^{48}\mathrm{Ca}(d, n)^{49}\mathrm{Sc}$ reaction has been studied at ${E}_{d}=20$ MeV. Angular distributions of differential cross sections have been obtained for 14 transitions to states in $^{49}\mathrm{Sc}$ up to an excitation energy of 7.1 MeV. A distorted-wave Born-approximation analysis has been made of the experimental data. With respect to states corresponding to the same proton single-particle orbital, relative values of derived spectroscopic factors are generally in good agreement with those obtained from ($^{3}\mathrm{He}$, $d$) reaction data. There are remarkable differences between the results from the $^{48}\mathrm{Ca}(d, n)^{49}\mathrm{Sc}$ reaction and the $^{48}\mathrm{Ca}(^{3}\mathrm{He}, n)^{49}\mathrm{Sc}$, however, regarding the dependence of the relative spectroscopic factors on proton single-particle orbitals.NUCLEAR REACTIONS $^{48}\mathrm{Ca}(d, n)^{49}\mathrm{Sc}$, $E=20$ MeV, neutron time of flight, $\ensuremath{\Delta}E=120$ keV.
