Abstract
The Kαh hypersatellite spectra of Mg, V, Cr, Mn, and Fe are measured with a plane crystal Bragg spectrometer for the first time in photon excitation. The experimental energies of the Kα2h lines are obtained and the energies of the Kα1,2 and Kα1,2h lines are calculated using a multiconfiguration Dirac-Fock program of Desclaux. The K-shell double photoionization cross sections are estimated from the experimental hypersatellite intensities. Results agree qualitatively with existing theoretical calculations based on the shake theory and correlated wave functions.Keywords
