Vector analyzing power and cross section for the reactionAr36(d→,p)Ar37

Abstract

Cross section and vector analyzing power for the reaction $^{36}\mathrm{Ar}(\stackrel{\ensuremath{\rightarrow}}{d},p)^{37}\mathrm{Ar}$ have been measured for an incident deuteron energy of 10.02 MeV. The data have been analyzed in the framework of the distorted-wave Born approximation. The $J$ dependence of the vector analyzing power permits unambiguous spin-parity assignments to be made for 19 states in $^{37}\mathrm{Ar}$ with excitation energies up to 8.40 MeV. Tentative spin assignments are made to the states with excitation energies 8.093 and 8.399 MeV. Most probable spin-parity values for the constituents of the unresolved (5.880 + 5.961) MeV and (7.246 + 7.282) MeV groups in the spectra are suggested from an analysis of the data. Spectroscopic factors are extracted using deuteron optical model potential parameters obtained from a simultaneous analysis of the elastic cross section and vector analyzing power data. Results of the analysis for the 2.217 and 7.131 MeV states indicate the possible importance of reaction processes other than the one-step stripping mechanism.NUCLEAR REACTIONS $^{36}\mathrm{Ar}(\stackrel{\ensuremath{\rightarrow}}{d},d)$, $\stackrel{\ensuremath{\rightarrow}}{d},p$, $E=10.02$ MeV; measured $\ensuremath{\sigma}(\ensuremath{\theta})$, $i{T}_{11}(\ensuremath{\theta})$; deduced $J$, $\ensuremath{\pi}$, $S$ by DWBA analysis.
