j-dependence in l = 1 transitions in Cr(d, p) reactions

Abstract

The j-dependence of several ; l = 1 transitions in the 50Cr(d, p)51Cr and 52Cr(d, p)53Cr reactions at 7.5 and 8.0 MeV deuteron bombarding energy, respectively, has been qualitatively described using the distorted-wave theory. This description required a rather different deuteron potential from that obtained by fitting elastic-scattering data which implies that the distorted-wave theory is not strictly valid. If the deuteron parameters are essentially the same for each transition, the angular distributions for J = 1 2 and J = 3 2 levels are systematically different at backward angles, and the difference is a consequence of the deuteron and proton spin-orbit interactions. The Lee-Schiffer rule may be interpreted in this manner. The transition to the 1.895 MeV level in 51Cr is found to violate the j-dependence rule probably because of unusually large corrections occurring in this case. Show more
