Observation of Desorbed Cluster Ions from the Surface of Solid Ne by Low Energy Ion Impact

Abstract

  Desorption of cluster ions (Ne_n⁺) from a surface of solid Ne following 1.2 keV Ar⁺ ion bombardment has been investigated. We have measured the desorption yield of the cluster ions as a function of thickness of Ne film. Kinetic energy measurement of mass-selected clusters is also presented. These results allow us to discuss the desorption mechanism of the cluster ions.
