在有心力守恒的情况下，给出了两粒子碰撞的能量与碰撞角之间的关系。它们是在实验室坐标系中导出的，因为这个坐标系对于解释实验结果至关重要。对相互作用定律的依赖性通过cm系统散射角的函数进入所获得的关系。给出了碰撞统计的一些注释，并导出了碰撞粒子在给定能量和方向变化时的碰撞截面。这些横截面可以用来确定描述各种物理过程的横截面。根据散射问题的截面，可以认为散射粒子的”衍射”图案是由于散射粒子的量子化状态，而不是相互作用定律。
The relations between the energies and angles for two-particle collisions are given for the case of conservative central forces. They have been derived in the laboratory system of coordinates, since this system is of prime importance for the interpretation of the experimental results. The dependence on the law of interaction enters the obtained relations through the function for the cm-system scattering angle. Some remarks on the statistics of encounters are given, and the cross sections for collisions in which the colliding particles experience given changes in energy and direction are derived. These cross sections can be used to determine the cross sections describing various physical processes. On the basis of the cross sections derived for the scattering problem, one can suggest that the" diffraction" pattern of scattered particles is due to quantized states of the scattering particles, rather than to the law of interaction.
