Abstract
We present a study on the 2p electron excitation in Al target atoms in very low energy asymmetric collisions with lighter Ne+ projectile ion s. We show that one of the L-shell vacancies originally present in Ne 2p3, created by double 4fsigma electron promotion from Ne 2p5 or 2p(5) 3s, can be transferred to the Al partner through a two-electron autoex citation mechanism. Our results provide an interesting interpretation for the previously observed lower threshold energies for target Al LMM Auger emission for Ne+ impact than for Ar+, Kr+, and Xe+.
