Jdependence of the vector analyzing power in theCa40(d→, p)Ca41reaction at 4 MeV

Abstract

The vector analyzing power for the $^{40}\mathrm{Ca}(\stackrel{\ensuremath{\rightarrow}}{\mathrm{d}}, \mathrm{p})^{41}\mathrm{Ca}$ reaction has been measured at 4.0 MeV. Data for transitions to a number of states in $^{41}\mathrm{Ca}$ are compared with the results of distorted-wave Born approximation calculations. The $j$ dependence of the vector analyzing power is shown to persist in spite of the low bombarding energy and the presence of compound nucleus formation. The data for the 3.61 MeV state lead to a spin assignment of ${j}^{\ensuremath{\pi}}={\frac{1}{2}}^{\ensuremath{-}}$. The present results support the conclusion that this state is a close doublet.NUCLEAR REACTIONS $^{40}\mathrm{Ca}(\stackrel{\ensuremath{\rightarrow}}{\mathrm{d}}, \mathrm{p})$, ${E}_{d}=4.0$ MeV; measured vector analyzing power $i{T}_{11}(\ensuremath{\theta})$ for transitions to states in $^{41}\mathrm{Ca}$ at ${E}_{x}=0.0, 1.94, 3.61, 3.94$ MeV.
