ATOMIC ELECTRON-EXCITATION PROBABILITIES DURING ORBITAL ELECTRON-CAPTURE BY THE NUCLEUS

Approximate probabilities of electron excitation (shakeup/shakeoff) from various atomic states during nuclear ns electron capture have been calculated in the sudden approximation, using Hartree-Fock wave functions. Total excitation probabilities are much lower than during inner-shell ionization by photons or electrons, and ns states are more likely to be excited than np states. This latter result is borne out by Kα x-ray satellite spectra.
