Observation of Multistep Inelastic Processes in Heavy-Ion-Induced Two-Neutron Transfer Reactions on Rare-Earth Nuclei

Abstract

Strong experimental evidence for the importance of multistep processes has been obtained from the reaction ${}_{}{}^{186}{}_{}{}^{}\mathrm{W}$(${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$, ${}_{}{}^{14}{}_{}{}^{}\mathrm{C}$)${}_{}{}^{184}{}_{}{}^{}\mathrm{W}$ at 70 MeV. The angular distributions are in good agreement with theoretical predictions and show dramatic influence from inelastic nuclear-Coulomb interference as well as from direct, two-step interference.
