Relativistic calculation of the K-LL Auger spectrum

Abstract

Relativistic calculations for the K-LL Auger spectrum are given for a wide range of atomic number. For the first time to our knowledge, a relativistic analogue of intermediate coupling with configuration interaction is applied to this spectrum. In the calculations use has been made of the binding energies of K and L electrons compiled by Sevier, the relativistic Slater integrals and relaxation term calculated by Larkins and the matrix elements for the K-LL transitions calculated by Bhalla and Ramsdale. Our results fit favourably with the experimental results tabulated in the review article of Burhop & Asaad (1972). Comparison of the relativistic Auger transition rates with the corresponding nonrelativistic values calculated with the matrix elements of Walters & Bhalla (1971) is also made.
