英文摘要	The photodissociation of Br-2 was investigated within the near-visible UV absorption band. Based oil the potential curves for the ground and low-lying excited states, the optical cross-sections for the discrete transitions of C(1)IIu, (BII0u+)-I-3, A(3)II(1u) <-(XEg+)-E-1 and their total energy absorption spectrum are derived, and the quantum yield of (Br+Br) channel are determined correspondingly. The one-diniensional Landau-Zener model is used to evaluate the behavior of curve crossing during photodissociation. The results indicate that the influence of nonadiabatic mechanism, which may be caused by the electronic-vibrational interplay between the B and C states, is negligibly small for the (Br+Br) channel. From the Landau-Zener modeling of the observed product recoil parameter beta((Br+Br)), the best-fit value of the coupling matrix element or coupling strength between the diabatic B and C state potentials is obtained.
