Abstract
Differential cross sections for18O elastic scattering and the (18O,16C) and (18O,17N) reactions on48Ca were measured at 102 MeV using a Q3D magnetic spectrograph. The transitions to the 7/2− ground state (g.s.) of49Sc and the 0+ (g.s.), 2+ (1.554 MeV), 4+ (2.675 MeV), and 6+ (3.198 MeV) states of50Ti were analyzed by DWBA calculations which include finite-range and recoil effects. Simple cluster-transfer calculations were done for all two-proton transfer transitions. For the 0+ (g.s.) transition a two-nucleon transfer code employing microscopic wave functions was also used. It was found that absolute cross sections for this kinematically well-matched transition were underrated by a factor of about 7 for a reasonable amount of configuration mixing in the nuclear states involved in this transition. This factor is very close to the value 5 derived for the similarly well-matched48Ca(18O,16O)50Ca reaction.
