Abstract: The dissociation dynamics of NaI molecule in femtosecond laser field has been investigated by employed the time-dependent quantum wave packet approach. Subjected to the influence of non-adiabatic effect, NaI molecule splits into two parts when the excited wave packet reaches to the crossing region RX. One part transfers to the ionic state V1, and another part on the repulsive state V2 will be dissociated into Na and I atoms. It is found that the dissociation probability depends on the velocity of the excited wave packet. And, its velocity can be altered by tuning the wavelength and width of laser field. Ultimately, it realizes the control of the dissociation dynamics of NaI molecule.

Key words: quantum control, non-adiabatic effect, wave packet, dissociation
