Classical photo-dissociation dynamics with Bohr quantization

Abstract

The standard classical expression of the state-resolved photo-dissociation cross section is not consistent with an efficient Bohr quantization of product internal motions. A new and strictly equivalent expression not suffering from this drawback is proposed. This expression opens the way to more realistic classical simulations of direct polyatomic photo-dissociations in the quantum regime where only a few states are available to the products.
