Abstract:
The dissociation dynamics of Br2 molecules induced by two femtosecond pump pulses are studied based on the calculation of time-dependent quantum wave packet. Perpendicular transition from XΣg+1 to AΠ1u+3 and Π1u+1 and parallel transition from XΣg+1 to BΠ0u+3, involving two product channels Br (P3∕22)+Br (P3∕22) and Br (P3∕22)+Br* (P1∕22), respectively, are taken into account. Two pump pulses create dissociating wave packets interfering with each other. By varying laser parameters, the interference of dissociating wave packets can be controlled, and the dissociation probabilities of Br2 molecules on the three excited states can be changed to different degrees. The branching ratio of Br*∕(Br+Br*) is calculated as a function of pulse delay time and phase difference.
