Zero-degree projectile Auger electron spectroscopy in energetic ion-atom collisions
Abstract
An overview is given of recent measurements of projectile Auger electrons obtained using the method of zero-degree spectroscopy. Experimentally, this method provides the following two distinct advantages. First, kinematic line broadenings of the projectile electrons are significantly reduced at zero degrees. Second, by using light target atoms outer-shell configurations of incident ions can be essentially retained during the production of an inner-shell vacancy. Thus, Auger states of a desired charge state can be studied selectively with sufficiently high resolution. Data reviewed here are Auger spectra from multiply-charged argon and neon ions with energies of several {MeV}/{amu}. Also, autoionization spectra of He atoms created via transfer-excitation are presented. In this case a resonance behavior is observed for the production of the (2p 2) 1 D state.
