摘要：

The fragmentation dynamics of H-2(+) molecular ions in intense laser fields is investigated by means of a high-precision ab initio method beyond the Born-Oppenheimer approximation Special attention is paid to the detailed Coulomb explosion (CE) mechanisms and dynamics through excited., vibrational states of H-2(+.) A kinetic-energy release (KER) spectrum and CE phenomenon is predicted, in which the kinetic-energy distribution of H+ ions exhibits a series of peaks separated by one, photon energy. A proposed scheme for observation of the KER spectrum and CE dynamics is presented.
