Relativistic effects in exclusive neutron-deuteron breakup

Nuclear Theory 2009-11-11 v1

Abstract

We extended the study of relativistic effects in neutron-deuteron scattering to the exclusive breakup. To this aim we solved the three-nucleon Faddeev equation including such relativistic features as relativistic kinematics and boost effects at incoming neutron lab. energies E_n^{lab}=65 MeV, 156 MeV and 200 MeV. As dynamical input a relativistic nucleon-nucleon interaction exactly on-shell equivalent to the CD Bonn potential has been used. We found that the magnitude of relativistic effects increases with the incoming neutron energy and, depending on the phase-space region, relativity can increase as well as decrease the nonrelativistic breakup cross section. In some regions of the breakup phase-space dynamical boost effects are important. For a number of measured exclusive cross sections relativity seems to improve the description of data.
