Fully close-coupled quantum scattering calculations of rotational energy transfer cross sections for the N,-He, Ar, and Xe collision systems have been performed at a number of collision energies up to 300 cm-'. The results of these calculations are then fitted using the energy-dependent AON fitting

โฆ Synopsis
A new fitting law for :he primary set of rate constants. .Q+_o, occurring in lOSA fxtorkation is prcscnted. Assuming thnt the interaction potential is donlioated by ZI single tern] of the Legendre polynonkd expansion. PA(cos 0). we find k~-,o = C[ (a/n) io_g(aht) -oh + I]. The two fitting parametersa and c are espressed in terms of the ran_re zmd strcr@b of the model potenrisl. The validity of this law is tested.
