V. I. Zhaba

摘要:

本文考虑了用相函数方法计算单道核子-核子散射。本文用相函数方法计算了核子-核子散射的下列相移:nn(1 S_0-,3 P_0-,3 P_1-,1D_2-,3F_3-态),pp(1 S_0-,3 P_0-,3 P_1-,1D_2-,3D_2-态)和np(1 S_0-,1 P_1-,3 P_0-,3 P_1-,1D_2-,3D_2-态)。计算已进行使用现实的核子核子潜力奈梅亨集团(NijmI,NijmII,Reid 93)和潜在的阿贡v18。所得到的相移是在良好的协议与其他方法的框架中得到的结果。利用所得到的相移,我们计算了完整的截面。我们的结果是在良好的协议,通过使用已知的相在文献中发表。根据散射相位的计算方法,计算之间的几率为:pp-0,2 - 6,3%和np-0,1 - 5,3%(NijmI,NijmII),pp-0,1 - 4,1%和np-0,1 - 0,4%(Reid 93),不超过4,5%(Argonne v18)。

英文摘要:

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).
