N2 - The transition probabilities of K alpha hypersatellite lines and energy shifts with respect to the corresponding diagram lines are computed using the Dirac-Fock model for several values of atomic number Z throughout the periodic table. The influence of the Breit interaction on the K alpha(h)(1)/K alpha(h)(2) line intensity ratio, K alpha(h)(1) and K alpha(h)(2) line energy shifts and K alpha(h)(1) to K alpha(h)(2) line energy splitting is evaluated. Double-K shell hole threshold values for selected elements with 23 <= Z <= 30, calculated within the same approach, are compared with available experimental results.
