Section 1.—The hypothesis that the electron has a magnetic moment was, as is well known,
first introduced to account for the duplexity phenomena of atomic spectra. More recently …

1. In a previous paper the author has applied the relativistic theory of the electron due to
Dirac to the problem of the scattering of electrons by atoms. The main purpose of the …

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 …

The scattering of a stream of charged particles by a spherically symmetrical electrostatic field
was first investigated, from the point of view of the wave mechanics, by Born. Various …
