vhoice Cross sections for multinucleon transfer reactions are measured at several angles in the reaction
88Sr(
12C,X) - X ranging from
9Be to
14C at an incident carbon-ion energy of 87.5 MeV. In case of single-nucleon transfer reactions, the measured angular distributions of cross sections in transition to the ground and low-lying states in the
87,89Sr and
89Y nuclei are described well in terms of finite-range DWBA calculations. The transfer probability obtained from the experiments to well-defined shell-model orbits forms the single-particle unit for evaluation of the mechanism in multinucleon transfer reactions. The analysis reveals a small enhancement of the transfer probability corresponding to a proton-pair stripping. The mechanism of one-step “direct” transfer of a cluster is predominant in deuteron and
3He transfer reactions. However, the transfer of a neutron pair seems to proceed through a sequential transfer of two neutrons.
