Relativistic Calculation of two-Electron one-Photon and Hypersatellite Transition Energies for $12leq Zleq30$ Elements

Energies of two-electron one-photon transitions from initial double K-hole states were computed using the Dirac-Fock model. The transition energies of competing processes, the K$alpha$ hypersatellites, were also computed. The results are compared to experiment and to other theoretical calculations.
