Formation and subsequent decay of very highly charged states of CO molecular ions has been studied in 97 MeV collisions between F<sup>8+</sup> and CO using a crossed beams apparatus by measuring the energy distributions of carbon and oxygen ions. The kinetic energies released (KER) upon dissociation of CO<sup>q+</sup> (q=2-10) ions have been investigated by means of large scale, ab initio configuration interaction molecular orbital calculations. Results indicate that dissociation via non-Coulombic potential energy curves of CO<sup>q+</sup> ions yields lower values of KER than would be expected from purely Coulombic considerations due to the significance of electronic charge density distributions in the internuclear region.
