✦ Synopsis

A theoretical analysis is given for the excitation transfer of Xe('P,) +N, (X IX ,') + Xe ( 'SO) + N, (B 'Qy). The analysis is based on (i} pure Coulomb interaction coupled with electron exchange and (ii) spin-dependent interaction between the collision partners. Both mechanisms can account for the observed R= 0 propensity at low impact energy when Xe is initially in the 'P, state.

The observed Q= 2 fine structure level of N, in the product can only be explained by the spin-dependent interaction. Collinear, perpendicular and skewed angle approaches of the atom-molecule configuration have been considered.
