Classical trajectories analysis, in a recent potential, are used to investi
gate the dynamics of the rotational excitation process Ar + Cl-2(j) --> Ar
+ Cl-2(j'). Differential cross section, mean energy transferred and the rai
nbow structure of the excitation process is presented, the results being co
mpared with the experimental data. The present work will also provide anoth
er test for the potential used, indicating which modification should be don
e to improve its quality. (C) 1999 Elsevier Science B.V. All rights reserve
