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 
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 
, involving a neutral
fragment.
