The transition probabilities of Kα 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 <I>Z</I> throughout the periodic table. The influence of the Breit interaction on the Kα<SUB>1</SUB><SUP>h</SUP>/Kα<SUB>2</SUB><SUP>h</SUP> line intensity ratio, Kα<SUB>1</SUB><SUP>h</SUP> and Kα<SUB>2</SUB><SUP>h</SUP> line energy shifts and Kα<SUB>1</SUB><SUP>h</SUP> to Kα<SUB>2</SUB><SUP>h</SUP> line energy splitting is evaluated. Double-K shell hole threshold values for selected elements with 23 ⩽<I>Z</I>⩽ 30, calculated within the same approach, are compared with available experimental results.
