The roles of Pauli correlations, channel couplings, and shake-off in ion-induced KLsup(V) and K2Lsup(V) multiple-vacancy production

Cross sections for target K-plus-L-shell multiple-vacancy production by ions can be inferred from experimental intensities. The theory of Ksup(n) Lsup(v) multiple-vacancy distributions has been generalized from the single-particle model (the statistically independent electron approximation) to the independent Fermi particle model. The Pauli correlations (electron exchange terms) are found to nearly cancel in many cases because of a tendency toward random phases. (orig./BRB)
