The linear and circular polarization of the Li(2p-2s) emission has been measured for Li ÷ collisions with cesiated and oxydized cesiated W(110) surfaces, Cs-W(110) and O/Cs-W(ll0), at impact energies below 1 keV for an incidence angle of 5 degrees with respect to the surface plane. The cesium coverage has been varied between zero and the saturation coverage at room temperature. Although the excitation of the projectile seems to occur in a binary collision with only one Cs adatom, the presence of the surface influences the total photon yield by Auger deexcitation, and the circular polarization by affecting the energetic separation of the Li(2p) substates close to the surface.

“…The analysis of the light emitted after the collisional excitation of the atom allows one to obtain a geometrical picture of shape, position in space and angular momentum of the atomic electron charge cloud. Such particle-photon coincidence experiments for the study of outer shell excitation in ion(atom)-atom collisions have been performed in the energy range of some keV [1,2] and at some 100eV [3]. The present work represents an alternative approach characterised as follows:…”

“…Two different experimental methods can be used to determine the shape of the electron charge distribution and its internal dynamics. The particle-photon coincidence technique has been applied to ion (atom)-atom scattering in the energy range of some keV [2,3] and some 100 eV [4]. For the study of Na*(3p)+Na--collisions we have used an equivalent experimental procedure.…”

Pronounced polarization effects have been observed in inelastic collisions of laser stateprepared Na*(3p, Mc) with Na § leading to Na*(3d) for the energy range EcM=20-45 eV. Using linearly polarized light the dependence of the inelastic process on the alignment of the electronic charge cloud of the Na*(3p) prior to the collision has been measured. In studies with left and right hand circularly polarized light the angular momentum transferred in the collision process has been determined. The results are compared with similar data for the 3p--,3s deexitation process studied previously [6].The density matrix of the Na*(3p) state has been evaluated with respect to the collisional excitation to Na*(3d). Semiclassical calculations based on the coupled channel impact parameter approximation using pseudopotentials [7] and nonadiabatic rotational coupling elements for the Na* system [12] have been performed. The agreement with the experimental results is good, in particular for the higher collision energies.
