In this work we report on studies of the dissociative ionization of CO and NO induced by 1-MeV H+, He+, and O+ projectiles. The time-energy spectroscopy (TES) technique is used to identify the dissociation fragments according to their mass-to-charge (m/q) ratios, and to record kinetic energy spectra for each fragment species. The spectra fragments with 1+, 2+, and 3+ charges show overlapping peaks for which energy assignments are made. In most case, the He+ and O+ projectiles appear to form dissociative states of CO2+ and NO2+ which decay into singly charged fragments. The H+ projectile appears to form CO+ and NO+ which subsequently dissociate into charged and neutral fragments. The dissociative states excited in this experiment are different from those reported in K-shell ionization studies.
