We present a complete theory of the scattering of a particle in a Yukawa potential when the screening length is much larger than the classical impact parameter for ${90}^{\circ }$ deflection and than the de Broglie length. The classical limit, the quantum limit, and the intermediate case are investigated, enabling an accurate determination of the argument of the Coulomb logarithm in the general case. The connection with previously published results is made.

汤川势的库仑对数精度

当屏蔽长度比传统的碰撞参数大得多时，我们提出了Yukawa势中粒子散射的完整理论。 ${90}^{\circ }$挠度大于de Broglie的长度。研究了经典极限，量子极限和中间情况，从而能够精确确定一般情况下的库仑对数论点。与先前发布的结果建立了联系。
