Abstract

The L-shell internal ionization accompanying L capture has been considered. Numerical calculations of the internal-ionization probabilities per L capture and the energy spectra of electrons ejected during this process are presented for low-energy transitions in high-Z elements. Screened relativistic hydrogenic wave functions are used. The effect of the presence of a hole resulting from electron capture is included in the screening constant for the daughter atom. It is shown that the ionization probability per L capture depends upon BiE0, where E0 is the transition energy of the ordinary electron capture and Bi is the Li-shell binding energy of the daughter atom (i=1,2,3). The calculated results also predict that observation of this process is possible when the K-shell internal-ionization process during K capture is forbidden energetically. Possible experiments to detect this phenomenon are briefly discussed.
