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

The excitation functions of ~(235)U(p,n)~(235)Np,~(235)U(p,2n)~(234)Np and~(235)U(d,2n)~(235)Np reactions were calculated and evaluated respectively. Up to now,the experimental data for ~(235)U(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 of~(235)U(d,2n)~(235)Np 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.
