Relativistic Calculation Of K$β$ Hypersatellite Energies and Transition Probabilities for Selected Atoms with 13<=Z<=80

Abstract

Energies and transition probabilities of K$β$ hypersatellite lines are computed using the Dirac-Fock model for several values of $Z$ throughout the periodic table. The influence of the Breit interaction on the energy shifts from the corresponding diagram lines and on the K$β\_{1}^{\rm h}$/K$β\_{3}^{\rm h}$ intensity ratio is evaluated. The widths of the double-K hole levels are calculated for Al and Sc. The results are compared to experiment and to other theoretical calculations.
