摘要：

The isotopic effect on nuclear dynamics in Coulomb explosion for various initial vibrational states of H-2(+) and HD+ in intense laser (80 fs, 800 nm 1 = 6.8 x 10(13)W/cm(2)) is theoretically investigated by numerically solving the time-dependent Schrdinger equation. The calculated results confirm that the effect we discussed by paying close attention to the comparative analysis of peak locations in the nuclear kinetic-energy-release spectra largely depends on the selection of the initial vibrational states. Furthermore, it is the special isotope effect case about the vibrational state nu = 5 that has been studied in depth. We also discuss the time-dependent spectrum at nu= 7, which can reveal the difference in nuclear wavepacket motion between H-2(+) and HD+ in the time region in which charge- resonance enhanced ionization takes place.
