${}_{}{}^{36,38}{}_{}{}^{}\mathrm{Ar}$(d¯,α${)}^{34,36}$Cl reactions induced by tensor polarized deuterons

Exact finite-range distorted-wave Born approximation analyses of cross section and vector and tensor analyzing power angular distributions for some ${}_{}{}^{36}{}_{}{}^{}$,38Ar(d→,α) transitions induced by 16 MeV polarized deuterons have been performed using full sd-shell model wave functions and including a D-state amplitude for the α particle. The L-mixing ratios R for several unnatural parity transitions have been determined from comparisons of the calculations with the tensor analyzing power data. Shell-model calculations are found to be in agreement with the experimentally obtained phases of R, while the predicted magnitudes agree well in some cases.
