STUDY OF MULTIPLE CAPTURE PROCESSES BY RECOIL ION MOMENTUM SPECTROSCOPY FOR 150 KEV NE10-AR COLLISIONS()

We report preliminary investigations of multiple electron capture in t he collision of 150 keV Ne10+ ions with Ar targets. These processes ca n be described by the following reaction: Ne10+ + Ar --> Ne-(10-s+) Ar-r+ + (r - s) e(-). The Ne10+ projectile removes r electrons from th e Ar target among which s electrons are stabilized on the projectile a nd (r - s) are ejected into the continuum. Distributions corresponding to the production of up to septuple-charged recoils were obtained in coincidence with the charge state (10 - s) of the scattered projectile s. Stabilization rates and average scattering angles were also derived from this experiment and given here as preliminary results.
