The time‐dependent‐wave‐packet method is applied to study the ionization of Br 2 molecule with four ionization processes. The ground state absorption makes the photoelectron to be left in the three final ionic states: Br 2 +( X 2 ∑ g + ), Br 2 +(A 2 ∏ u ), and Br 2 +( B 2 ∑ u + ), and each population of these ionic states is related with the laser intensities. The information of the dissociation can be got by analyzing the photoelectron features of the transient wave packet, which also suggests that an ionization process occurs during the dissociation, and the Br atoms that mainly resulted from the dissociation of Br 2 (C 1 ∏ u ) are ionized at later time delays as the dissociation is nearly complete. © 2007 Wiley Periodicals, Inc.
