Measurement of Br photofragment orientation and alignment from HBr photodissociation: Production of highly spin-polarized hydrogen atoms
TP Rakitzis, PC Samartzis, RL Toomes… - The Journal of …, 2004 - pubs.aip.org
The orientation and alignment of the P 2 3/2 and P 2 1/2 Br photofragments from the
photodissociation of HBr is measured at 193 nm in terms of aq (k)(p) parameters, using slice
imaging. The A 1 Π state is excited almost exclusively, and the measured aq (k)(p)
parameters and the spin-orbit branching ratio show that the dissociation proceeds
predominantly via nonadiabatic transitions to the a 3 Π and 1 3 Σ+ states. Conservation of
angular momentum shows that the electrons of the nascent H atom cofragments (recoiling …
