We have applied the relativistic Fock-space coupled-cluster theory to calculate Kα transition properties of F-like ions for a number of elements throughout the periodic table. A state-specific form of the coupled-cluster method for electron detachment has been used to calculate the Kα energies and line strengths. The computed energies are used to determine the transition probabilities for more than 30 elements to study the Z dependencies for Z=10 79 . This application of a variant of coupled-cluster theories to study the Kα transitions should be the most accurate determination of these transition probabilities to date. The most important finding in this paper is the crossover of Kα1 and Kα2 at high Z . In general, for lighter ions, Kα2 is higher in magnitude than Kα1 , but at Z=41 42 they are switched. In addition, the results demonstrate the variation with Z of the Kα2 A values along the Periodic Table. The astrophysical significance in the analysis of Kα lines, important in x-ray astronomy, is pointed out.
