PRODUCT ENERGY-DISTRIBUTIONS AND ANGULAR-MOMENTUM DISPOSAL IN HEAVY-HEAVY-LIGHT REACTIONS VIA THE CPOAM MODEL

The collision-energy dependence of both product energy and angular mom entum disposal of the HHL B + OH --> BO + H and Be + HF --> BeF + H re actions has been analysed in the light of the CPOAM (constant product orbital angular momentum) model, which allow estimates of the division of angular momentum disposal between product rotation and orbital mot ion. We have carried out the analysis by introducing the dependence of reaction cross section (sigma(R)) on translational energy (E(trans)) through different excitation function models. Results thus obtained ha ve been compared with those corresponding to three-dimensional (3D) qu asiclassical trajectory (QCT) calculations on the corresponding potent ial energy surfaces (PES).
