Rate constant calculations for the vibrational deactivation of N2(v = 1) by helium atoms, employing the coupledstates approximation and the potential energy surface of Banks et aI., are presented and compared with experiment in the temperature range 100-300 K. The low impact energy behaviour of the
Cross secfiws and rate constants for the vibrat$onal Maxation of H&J = I,i= I) in collisions with 4He were determined using the coupled states method with a fulIy-converged channel basis. The interaction potential was taken to be that of Gordon and Secrest with the elastic matrix elements modified t
Fully converged quantum cross sections for 4He-D2 (u= l,i=O) vibrational reliaxation were determined using the coupled-states method and a modikied version of the Gordon-Secrcst surface. First-order forbidden rotational transitions play a si@fkant role, comparable to that observed previously for the
The vibrational relaxation of ortho-para-Hz in collisions with 4He has been studied in the interval 300-50 K. At 300 K the ortho Hz -He and para Hz-He rates are identical within experimental error. In the low temperature range ko~z\_~e
