Abstract
Single-nucleon transfer reactions induced by 115.9-MeV ions incident on targets of , , , , , and have been studied with the primary objectives of elucidating the reaction mechanism and investigating the utility of such reactions as spectroscopic probes. Reaction-product energy spectra from the (, ) and (, ) transfer reactions were recorded simultaneously for each target using a and particle identification system which permitted isolation and study of individual residual states. All reactions exhibited highly selective population of residual states, consistent with a particularly simple reaction model involving the direct transfer of a nucleon to an unexcited target core. Evidence was adduced for a mechanism favoring the population of high-angular-momentum states of this configuration. For all targets, ratios of measured cross sections for neutron and proton transfer reactions leading to analog residual states were used to obtain the relative + and + parentage of the ground state on the assumption of charge independence throughout the reactions. Calculations based on available -shell wave functions were found to be in good accord with the experimental results.
