Meson retardation in deuteron photodisintegration above pi-threshold
arXiv:nucl-th/9709048 · doi:10.1016/S0370-2693(97)01532-3
Abstract
Photodisintegration of the deuteron above pi-threshold is studied in a coupled channel approach including N Delta- and pi d-channels with pion retardation in potentials and exchange currents. A much improved description of total and differential cross sections in the energy region between pi-threshold and 400-450 MeV is achieved.
