摘要：

The dissociation of COq+ ions (q less than or equal to 3) produced in collisions of 2-10 keV amu(-1) He2+ ions with CO has been studied by time-of-flight methods. From the time-of-flight spectra the energy released in the dissociation process is determined. Our results for the kinetic energy release of CO2+ and CO3+ ions are compared with the results of other ionization methods. Clear differences are observed. We observe a counterintuitive dependence of the kinetic energy release on the velocity of the He2+ ions, i.e. the kinetic energy release increases with decreasing velocity.
