计算了具有任意径向核电荷分布的球核之间的库仑相互作用。所有这些实际的库仑势都是用解析表达式给出的，可以立即应用。所以在任何情况下都不需要对库仑积分进行数值计算。电荷分布参数取自电子散射分析。所使用的电荷分布的库仑自能也以封闭形式进行了解析计算。对于许多核-核对，将实际电荷分布得到的库仑势与通常用于各种核-核光学模型计算的库仑势进行了比较。在此基础上，详细讨论了如何为不同的近似选择一致的库仑参数。
The Coulomb interaction between spherical nuclei having arbitrary radial nuclear charge distributions is calculated. All these realistic Coulomb potentials are given in terms of analytical expressions and are available for immediate application. So in no case a numerical computation of the Coulomb integral is required. The parameters of the charge distributions are taken from electron scattering analysis. The Coulomb self-energies of the charge distributions used are also calculated analytically in a closed form. For a number of nucleus-nucleus pairs, the Coulomb potentials derived from realistic charge distributions are compared with those normally used in various nucleus-nucleus optical model calculations. In this connection a detailed discussion of the problem how to choose consistently Coulomb parameters for different approximations is given.
