| 摘 要： | Wave packet dynamics of the Li2 molecule are investigated
by using the time-dependent quantum wave packet method, and the
time-resolved photoelectron spectra of the Li2 molecule are
calculated. The time-resolved wave packet theory is used to
reasonably interpret the phenomena of the photoelectron spectra for
different parameters. Our calculation shows that the loss of the
wave packets in the shelf state area of E{ }^1\Sigmag^ +
plays a prominent role in the process of photoionization with the
increase of the delay time. Moreover, the oscillation of the wave
packet on the E{ }^1\Sigmag^ + curve symbolizes a
decreasing process of energy.
