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,I=6.8×10^(13)W/cm^(2)) is theoretically investigated by numerically solving the time-dependent Schrodinger 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 v=5 that has been studied in depth.We also discuss the time-dependent spectrum atυ=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.
