英文摘要	we have discussed a weak ionization channel characterized by the kinetic energy release spectra of the protons from coulomb explosion with the sum energy over 10 ev from a hydrogen molecular ion for various vibrational states in infrared pulses. after franck-condon averaging of the contributions for various vibrational states, a 'shoulder'-like cutoff structure has been obtained which is consistent with the experiment. for longer pulses, a multi-peak structure is obvious for the upsilon = 0 state and attosecond extreme-ultraviolet pulses were adopted to search the essential physical dynamics. the reproductions of the kinetic energy release spectra from extreme-ultraviolet light indicate that the high kinetic energies of the protons must be due to the direct multi-photon ionizations. the origin of the multi-peak structure has also been investigated by the extreme-ultraviolet pulses. time-dependent spectra reveal the nuclear wavepacket motion and the time region when charge-resonance-enhanced ionization takes place. competitions between direct multi-photon ionizations and charge-resonance-enhanced ionizations have also been discussed for various intensities and pulse durations for the upsilon = 0 state.
