Abstract
A value of 39.6 eV is measured for the lowest double ionisation energy of CO by means of a new ion translational energy loss spectrum of H- products from 3 keV double electron capture collisions between H+ and CO measured with enhanced resolution. New ab initio molecular orbital calculations with configuration interaction indicate that the lowest energy state of CO2+ accessible in such collisions possesses 1 Sigma + symmetry.Keywords
