Calculation of phases of np- scattering up to Tlab=3 GeV for Reid68 and Reid93 potentials on the phase-function method

Abstract

For calculation of the single-channel nucleon-nucleon scattering a phase-functions method has been proposed. Using a phase-functions method the following phase shifts of np- scattering numerically for 1S0-, 1P1-, 3P0-, 3P1-, 1D2-, 3D2-, 1F3-, 3F3-, 1G4-, 3G4- states are calculated. The calculations has been performed using realistic nucleon-nucleon Reid68 and Reid93 potentials. Obtained phase shifts for energy up to 350 MeV are in good agreement with the results obtained in the framework of other methods. Using the obtained phase shifts we have calculated the full cross-section np- scattering.
