Radiative electron rearrangement: a proposed description for low-energy satellites observed in ion-atom collisions

Abstract
The authors propose a satellite sequence as an explanation of the low-intensity peaks observed just below the energy of the K alpha 1,2 normal X-ray line. The sequence, (1s)-1(2p)-n to (2s)-2(2p)-n+1(n=1-4) radiative electron rearrangement (RER), gives good agreement with previously measured peak energies for Z between 11 and 22.
