✦ Synopsis

Quantum close-coupling c3Icuhtions are presented which verify that the rotational polartriution observed in recent experiments on NO-Ag(I 11) scattering is due primarily to rzv conservation. However a dramatic dependena of rotational transitions on initial q in some surfwe collisions is also indicated by the calculations and may be experimentally obserxtble.

If the collisional ionization is chiefly due to energy transfer from the polar-molcculc rotation to an electron in a high Rydberg state of the atom, then theory predicts that the cross section averaged over a thermal distribution of rotational states should show step-like structure as a function of
