Relativistic Effects in Neutron-Deuteron Elastic Scattering

摘要

We solved the three-nucleon (3N) Faddeev equation including relativistic features at incoming neutron lab energies El?b = 28, 65, 135 and 250 MeV Those features are relativistic kinematics, boost effects and Wigner spin rotations As dynamical input a relativistic nucleon-nucleon (NN) interaction exactly on-shell equivalent to the AV18 NN potential has been used The boost effects are significant at higher energies The effects of Wigner rotations for elastic scattering observables were found to be small There are rather small effects in the cross section, which are mostly restricted to the backward angles.
