  For calculation of the single-channel nucleon-nucleon scattering a
phase-functions method has been considered. Using a phase-functions method the
following phase shifts of a nucleon-nucleon scattering are calculated
numerically: nn (1S0-, 3P0-, 3P1-, 1D2-, 3F3- state), pp (1S0-, 3P0-, 3P1-,
1D2- state) and np (1S0-, 1P1-, 3P0-, 3P1-, 1D2-, 3D2- state). The calculations
has been performed using realistic nucleon-nucleon potentials Nijmegen groups
(NijmI, NijmII, Reid93) and potential Argonne v18. Obtained phase shifts 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. Our
results are in good agreement with those obtained by using known phases
published in literature. The odds between calculations depending on a
computational method of phases of scattering makes: 0,2-6,3% for pp- and
0,1-5,3% for np- scatterings (NijmI, NijmII), 0,1-4,1% for pp- and 0,1-0,4% for
np- scatterings (Reid93), no more than 4,5% (Argonne v18).
