建立了刚性旋转体的散射理论，其中考虑了旋转体不同能级之间的耦合，得到了不依赖于磁量子数的各种弹性和非弹性截面的显式表达式。文中描述了几种近似，特别注意了重粒子的散射，结果表明，在低温下，相互作用中与方位有关的部分可能比球对称部分更重要。我们还研究了低能电子的散射，数值积分了一些具有代表性的方程，以说明取向依赖的影响。
A theory of scattering by a rigid rotator in which the coupling between the different energy levels of the rotator is taken into account is formulated and explicit expressions, which do not depend upon the magnetic quantum numbers, are obtained for various elastic and inelastic cross-sections. Several approximations are described, particular attention being paid to the scattering of heavy particles for which it is shown that at low temperatures the orientation-dependent part of the interaction may be more important than the spherically symmetric part. The scattering of low-energy electrons is also investigated and some representative equations are integrated numerically to illustrate the effect of the orientation dependence.
