Two-Body Effects and Neutron Polarization in the ReactionH2(γ, n)Hat Low Energies

The neutron polarization in the reaction ${}_{}{}^2{}_{}{}^{}\mathrm{H}(\gamma , n)\mathrm{H}$ is calculated by incorporating the two-body charge- and current-density effects in the traditional theory. The calculations are carried out for a number of recent and old two-nucleon potentials. Clear evidence is provided that even at very low energies a serious discrepancy between theory and experiment exists.
