Sensitivity of (d , p ) Reactions to High n -p Momenta and the Consequences for Nuclear Spectroscopy Studies
Abstract
Theoretical models of low-energy (d , p ) single-neutron transfer reactions are a crucial link between experimentation, nuclear structure, and nuclear astrophysical studies. Whereas reaction models that use local optical potentials are insensitive to short-range physics in the deuteron, we show that including the inherent nonlocality of the nucleon-target interactions and realistic deuteron wave functions generates significant sensitivity to high n -p relative momenta and to the underlying nucleon-nucleon interaction. We quantify this effect upon the deuteron channel distorting potentials within the framework of the adiabatic deuteron breakup model. The implications for calculated (d , p ) cross sections and spectroscopic information deduced from experiments are discussed.
