Final-state interaction between nucleons in elastic deuteron breakup within the three-body potential model

Abstract

The diffraction deuteron breakup has been investigated within the three-body potential model, where the final-state interaction between nucleons is described nonperturbatively with respect to the pn potential. The triple differential cross section of the (d, pn) reaction on 40Ca at deuteron energies of 140, 200, and 270 MeV and small emission angles of nucleons have been calculated for two schemes of the kinematically complete experiment. Noneikonal and nonadiabatic corrections to the cross section are small and do not change the shape of the peak in the proton energy spectra.
