Rotationally inelastic collisions of LiH with He: a quasi-classical dynamics study

The results of quasi-classical trajectory calculations on the He-LiH collision system using a recently computed BSSE (Basis Set Superposition Error) free potential energy surface are presented. Rotationally inelastic cross-sections are compared with quantal results obtained with the same potential and with experimental measures. A detailed comparison with classical results determined on a previous potential energy surface is carried out. The differences between simulations are discussed and related to the different anisotropies of the two surfaces.
