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
Relativistic three-nucleon calculations within the Bethe-Salpeter approach
The relativistic properties of the three-nucleon system are investigated
using the Faddeev equations within the Bethe-Salpeter approach. The
nucleon-nucleon interaction is chosen in a separable form. The Gauss quadrature
method is used to calculate the integrals. The system of the integral equations
are solving by iterations method. The binding energy and the partial-wave
amplitudes (1S 0 and 3S 1) of the triton are found
