THE EVALUATIONS AND THEORETICAL CALCULATIONS OF 235U（p,n）235Np,235U（p,2n）234Np AND 235U（d,2n）235Np REACTION CROSS SECTIONS

摘要

正 The excitation functions of 235U（p,n）235Np,235U（p,2n）234Np and235U（d,2n）235Np reactions were calculated and evaluated respectively. Up to now,the experimental data for 235U（p,n）and（p,2n）reactions in theenergy region from threshold to 25 MeV have not been found;Argonne Na-tional Lab.（ANL）and Lawrence Radiation Lab.at Berkeley（BRK）havemeasured the excitation function of235U（d,2n）235Np reaction respectively;buttheir data appear in great difference. New experimental data have to wait for being measured for unpredictabletime delays.In order to meet the practical requirements,the theoretical calcula-tion and experimental evaluation are carried out.
