Abstract

On the basis of the liquid drop model of atomic nuclei, an account is given of the mechanism of nuclear fission. In particular, conclusions are drawn regarding the variation from nucleus to nucleus of the critical energy required for fission, and regarding the dependence of fission cross section for a given nucleus on energy of the exciting agency. A detailed discussion of the observations is presented on the basis of the theoretical considerations. Theory and experiment fit together in a reasonable way to give a satisfactory picture of nuclear fission.

核裂变的机制

在原子核液滴模型的基础上，叙述了核裂变的机理。特别地，对于裂变所需的临界能量在原子核之间的变化，以及对于给定原子核的裂变截面对激励机构能量的依赖性，得出了结论。在理论考虑的基础上，对观测结果进行了详细的讨论。理论和实验以一种合理的方式相结合，给出了一幅令人满意的核裂变图。
