We have measured the polarization of the Kα′ [(1s-12p-1)P11] to [(2p-2)S01] x ray from an Al target following bombardment by various ion beams at several different incident energies. The polarization of the Kα′ x ray is a measure of the ratio of the 2p substate populations σ1 (ML=±1) and σ0 (ML=0) of the P11 state. We compare our results with recent collision-theory calculations which predict nonstatistical substate populations for simultaneous K- and L-shell ionization.
