Abstract
Several models of ion emission predict that the heavier isotopes of a given element will be under-represented in the SIMS mass spectrum. Isotope effect measurements by the Orsay group [1,2] and by SHIMIZU and HART [3] have demonstrated this behavior. The present study supplements this work with additional velocity- dependent measurements of the isotope effect in various materials. Negative ion emission and dimer formation are also investigated. Several interesting experimental observations are reported here.
