One-rank interaction kernel of the two-nucleon system for medium and high energies
A new version of the separable kernel of the nucleon-nucleon interaction in
the Bethe-Salpeter approach is presented. The phase shifts are fitted to recent
experimental data for singlet and uncoupled triplet partial waves of the
neutron-proton scattering with total angular momenta J=0,1. The results are
compared with other model calculations.Comment: 10 pages, 5 figures, 3 table
On the Relativistic Separable Functions for the Breakup Reactions
In the paper the so-called modified Yamaguchi function for the Bethe-Salpeter
equation with a separable kernel is discussed. The type of the functions is
defined by the analytic stucture of the hadron current with breakup - the
reactions with interacting nucleon-nucleon pair in the final state (electro-,
photo-, and nucleon-disintegration of the deuteron).Comment: 4 pages, 2 figures, to be published in EPJ Wo
