Landés g-factor and g-formula

Abstract

In 1919, the young theoretician Alfred Landé (1888--1976) in Frankfurt am Main showed in his habilitation thesis that satisfactory agreement could be reached between observed splittings of spectral lines in the ► Zeeman effect if one assumed that, in general, ► electrons contribute more to the total energy of the system than had been expected according to classical electron theory.
