摘要：

CO+ molecular ion excitation induced by 6.7 MeV/amu Xe44+ ion impact was studied using recoil ion momentum spectroscopy. The Kinetic Energy Release (KER) distribution clearly shows the population of CO+* highly excited states. Excellent agreement is observed when comparing this distribution to previous low lying states calculation. Surprisingly high KER components were present in our spectra with values as high as 29 eV. The simple Coulomb model is obviously unable to explain the measured fragmentation energies for the process CC+* --> C+ + O, involving a neutral fragment.
