Abstract
Inner shell states of CO have been studied using an electron impact te chnique at low values of incident energy. The decay of the inner-shell excited triplet state, (1s sigma(c))(-1)(2p pi)(1,3)Pi, has been obse rved for the first time with vibrational resolution, via its decay to ionic states of the molecule. The vibrational profiles are observed to broaden and shift to higher energies close to threshold. This behavio ur is explained as a molecular PCI effect.
