Mg 2p ionization by electron impact

The ionization of Mg 2p by electron impact has been studied at about 400 and 1000 eV incident energy and small momentum transfer via (e,2e) experiments. Two kinematical conditions have been chosen in order to study the coincidence angular distribution in the case where either only the direct 2p ionization contributes or the decay of the 2p core hole plays a role, too. The results have been compared with distorted-wave Born approximation calculations.
