Predissociation Dynamics of Br(2) in the [(2)Π(1/2)](c)5d; 0(g)(+) and [(2)Π(3/2)](c)6d; 0(g)(+) Rydberg States by Velocity Map Imaging Study

[Image: see text] We investigated the predissociation dynamics from the [(2)Π(1/2)](c)5d; 0(g)(+) and [(2)Π(3/2)](c)6d; 0(g)(+) Rydberg states of Br(2) using the velocity map imaging technique. Two-dimensional scattering images of the fragmented Br(+) exhibited an isotropic feature upon the excitati...

description [Image: see text] We investigated the predissociation dynamics from the [(2)Π(1/2)](c)5d; 0(g)(+) and [(2)Π(3/2)](c)6d; 0(g)(+) Rydberg states of Br(2) using the velocity map imaging technique. Two-dimensional scattering images of the fragmented Br(+) exhibited an isotropic feature upon the excitation of these Rydberg states. Analysis of the total kinetic energy release suggested the existence of the predissociation pathways to the dissociation limits of Br(5s, (4)P(3/2)) + Br(4p, (2)P(3/2)) and Br(5s, (4)P(5/2)) + Br(4p, (2)P(3/2)) via the 0(g)(+) ion-pair states that interact with the lower and/or excited-core Rydberg states lying at long internuclear distance regions thorough the avoided crossing.
