Abstract
The multirank separable kernels of the neutron-proton interaction for uncoupled S and P partial waves (with the total angular momentum J = 0, 1) are proposed. Two different methods of a relativistic generalization of initially nonrelativistic form factors parametrizing the kernel are considered. Using the constructed kernels the experimental data for phase shifts in the elastic neutron-proton scattering for the laboratory energy up to 3 GeV and low-energy parameters are described. The comparison of our results with other model calculations are presented. © 2009 Elsevier B.V. All rights reserved.
