| 摘 要： | Wave packet dynamics of the Li2 molecule are investigatedby using the time-dependent quantum wave packet method, and thetime-resolved photoelectron spectra of the Li2 molecule arecalculated. The time-resolved wave packet theory is used toreasonably interpret the phenomena of the photoelectron spectra fordifferent parameters. Our calculation shows that the loss of thewave packets in the shelf state area of E{ }^1Sigmag^ + plays a prominent role in the process of photoionization with theincrease of the delay time. Moreover, the oscillation of the wavepacket on the E{ }^1Sigmag^ + curve symbolizes adecreasing process of energy.
