在8- 32 MeV能量范围内研究了低能质子诱发{sup 233}U，{sup 235}U，{sup 236}U，{sup 237}Np，{sup 239}Pu，{sup 242}Pu，{sup 244}Pu，{sup 241}Am和{sup 243}Am裂变的质量产额曲线。比较了不同中子数的复合核在相同激发能量和相同电荷下的质量产额曲线的总体特征。从轻、重不对称峰的加权平均质量数、重不对称峰的半高宽、峰谷比等方面对结果进行了讨论。
Mass yield curves in low-energy proton-induced fission of {sup 233}U, {sup 235}U, {sup 236}U, {sup 237}Np, {sup 239}Pu, {sup 242}Pu, {sup 244}Pu, {sup 241}Am, and {sup 243}Am were investigated in the energy range of 8--32 MeV. The gross features of mass yield curves were compared either at the same excitation energy or for the same charge of the compound nucleus with different neutron number. The results are briefly discussed in terms of (1) the weighted mean mass number of the light and heavy asymmetric peak, (2) the FWHM of the heavier asymmetric peak, and (3) the peak-to-valley ratio.
