Abstract

Rare gas dimers formed when a fast beam of X//2** plus (X equals He, Ne, Ar) is neutralized in the reaction X//2** plus plus K//(//g//) yields X//2* plus K** plus have been studied by neutralized ion beam techniques. From measurements of the kinetic energy released in the dissociation of X//2* and with consideration of available spectroscopic information, it is proposed that the neutral dimers are formed initially in their first excited singlet and triplet electronic states. Ion beam attenuation cross-sections for He//2** plus , Ne//2** plus , and Ar//2** plus are 250, 180, and 80 A**2, respectively, indicating that electron transfer from K//(//g//) is a highly efficient process.
