Abstract

KRAMERS' well-known absorption law1, long used by astrophysicists in their calculations of the opacity of stellar material, was first derived from classical mechanics and the correspondence principle, and may be stated thus: where αv is the atomic coefficient of continuous absorption, Z is the effective atomic number, λ is the wave-length in cm., n is the quantum number, an is the statistical weight of the nth state, and g is a factor very nearly unity.
