Physical mechanisms and scaling laws of K-shell double photoionization.
We report on the photon energy dependence of the K-shell double photoionization (DPI) of Mg, Al, and Si. The DPI cross sections were derived from high-resolution measurements of x-ray spectra following the radiative decay of the K-shell double vacancy states. Our data evince the relative importance of the final-state electron-electron interaction to the DPI. By comparing the double-to-single K-...

متن کاملInterference effects in L-shell atomic double photoionization
Angular correlation pattern in two-electron continuum is very similar in double photoionization (DPI) of a neutral atom γ + A → A + 2e− and electronimpact ionization of the corresponding singly charged ion e− + A → A + 2e− . This allows us to identify and to interpret interference effects in DPI of various L-shell atomic targets such as the metastable He* 1s2s S and the ground state Li 1s2s and...
متن کاملSatellite intensities in the K-shell photoionization of CO.
A recently proposed scheme for calculating E-shell ionization cross sections in atoms and molecules using the relaxed-core Hartree-Pock (RCHF) approximation is extended to the treatment of shakeup processes. As an example, this scheme is applied to the m-~* satellites in the C ls photoelectron spectrum of CO. These results for the (SO, S1) pair of ~-~* satellite states reveal strong interferenc...
متن کاملDouble K -shell photoionization and hypersatellite x-ray transitions of 12 Z 23 atoms
Single-photon double K-shell ionization of low-Z neutral atoms in the range 12 Z 23 is investigated. The experimental method was based on measurements of the high-resolution Kα hypersatellite x-ray spectra following the radiative decay of the K-shell double-vacancy states excited by monochromatic synchrotron radiation. The photon energy dependence of the double K-shell ionization was measured o...
