Abstract
Abstract.:Neon dimer ions undergo spontaneous dissociation (metastable decay) severalmicroseconds after formation by electron impact ionization of neon clusters.In this contribution we compare the kinetic energy release distribution(KERD) of the previously reported isotopomer 20 Ne2 + with thatof 22 Ne2 + . The heavy isotopomer shows the same two componentsin the KERD as the lighter ones. However, the high-energy component that isdue to electronic pre-dissociation is reduced in intensity. The decrease isattributed to a reduced predissociation rate from the II(1/2u) state intoI(3/2u).
