The transfer of vibrational energy has been the topic of active experimental and theoretical
study for many years. Increasing technological progress has recently made possible the
study of such processes on the microscopic, molecular level. It is becoming feasible to
characterize the detailed rare constants from a given internal level of the reactants to a
given internal level of the products [1].
The methods of the quantum theory few-body scattering based on the Faddeev-
Yakubovsky equations [1] in momentum and configuration space are present [2,3] and
applied to the calculation of vibrational exiting in collision electrons and atoms with
molecules H 2 , N 2 , Li 2 , Na 2 , HCl, DCl, HBr,DBr, HJ, DJ.
The results of this calculations are compered with available experimental data [1,4]
and other calculation [2-4].
