本文研究的是在原子或原子核不受激发的情况下，单电子被原子散射的过程。如果在此过程中辐射效应被负反射，则实验室系统中散射电子的能量仅取决于传递给反冲原子的能量。对于低能电子，原子反冲可以忽略不计，实验室系统中电子的初始能量和最终能量大致相等。对于高能电子和大散射角，原子后坐力不可忽略，实验系统的初始电子能量明显小于初始电子能量。与这种散射过程有关的大量计算已经成为可能，部分原因是这个过程占主导地位，而且比电子与物质相互作用中涉及的大多数其他过程不那么复杂。关于这一过程最重要的早期总结之一是由莫特和梅西（m49）给出的，他们提出了伯恩和
This survey is concerned with the process of single electron scattering by an atom without excitation of the atom or the nucleus. If radiative effects are neg-lected in this process, the energy of the scattered electron in the laboratory system depends only on the energy transferred to the recoiling atom. For lowenergy electrons, the atomic recoil is negligible, and the initial and 6nal electron energies in the laboratory system are approximately equal. For high-energy electrons and large scattering angles, the atomic recoil is not negligible, and the 6nal electron energy in the laboratory system is measurably smaller than the initial electron energy.Extensive calculations pertaining to this scattering process have become available, partly because the process dominates and is less complicated than most of the other processes involved in the interaction of electrons with matter. One of the most important early summaries concerning this process has been given by Mott and Massey (M 49), who presented Born and
