Faddeev calculations of proton-deuteron radiative capture with exchange currents

Abstract

pd capture processes at various energies have been analyzed based on\nsolutions of 3N-Faddeev equations and using modern NN forces. The application\nof the Siegert theorem is compared to the explicit use of $\\pi$- and\n$\\rho$-like exchange currents connected to the AV18 NN interaction. Overall\ngood agreement with cross sections and spin observables has been obtained but\nleaving room for improvement in some cases. Feasibility studies for 3NF's\nconsistently included in the 3N continuum and the 3N bound state have been\nperformed as well.\n
