对５—３００ ＭｅＶ 能区质子与天然铅的各种反应截面进行了计算，在符合多种实验数据的基础上，预言了长寿命放射性核的累积产生截面及其随质子入射能量的变化和中子多重数。在分析实验数据的基础上，给出了中能质子引发天然铅核裂变质量分布的经验公式，计算了电荷分布，并将计算结果与实验数据进行了比较。
The various cross sections of 5-300 MeV energy protons and natural lead were calculated. Based on the experimental data, the cumulative cross sections of long-lived radionuclides and their variations with the incident energy of protons were predicted Sub-multiple number. Based on the analysis of the experimental data, an empirical formula for the mass distribution of natural lead fission induced by medium energy protons is given, and the charge distribution is calculated. The calculated results are compared with the experimental data.
