Summary:The invention relates to a nucleon and nucleon elastic scattering angle distribution calculation method, and belongs to the field of nuclear science and nuclear data, and the method comprises the steps: obtaining the phase shift and mixing parameters of each partial wave along with the energy change based on high-precision nuclear force calculation, inputting a nucleon-nucleon scattering type and an incident energy list, and carrying out the calculation; summing each partial wave to obtain a scattering cross section corresponding to an incident energy list, considering a scattering amplitude and a total angular momentum combination conjugated with the scattering amplitude to obtain an L-order Legendre polynomial coefficient, namely obtaining nucleons and nucleon elastic scattering angle distribution, and converting the nucleons and the nucleon elastic scattering angle distribution into an ENDF-6 format document for convenient application. By adopting the method disclosed by the invention, the neutron-neutron
