“…Values for these binding energies are obtained by scaling from correlation diagrams [38]. The adiabatic impact parameters calculated from this re-lation are in good agreement with the measured positions of the maxima in b. PL(b) in [34,37,25].…”

“…The main contribution to the folding integral comes therefore from the region where b.PL(b ) has the maximum. On the other side one knows [25,[33][34][35][36][37] that at large b L-vacancy production in near symmetric collision systems occurs via excitation of the 4f~-molecular orbital. At our collision velocities the 4fa cannot be assumed to behave adiabatically so that direct excitation of the 4for electrons should be at large b the dominant L-vacancy production mechanism.…”

K-vacancy production probabilities Pro(b) were measured with gas and solid targets by K-x-ray particle coincidences (impact parameter b is determined by the particle the PK(b) from solid targets are strongly influenced by a multiple collision effect, where projectile L-vacancies seem to be produced in collisions before K-vacancy production. However, this effect cannot be understood just by a two collision process where Lvacancy production and 2p~-2pa rotational coupling occurs in consecutive collisions.

“…Figure 2 shows the calculated impact parameter dependence of the excitation probability for 200, 400 and 700 keV collision energy. The calculated probability corresponds to one incoming 3dfi vacancy and is defined as the (unweighted) average over the usual time-even and timeodd channels [9]. It is seen from Fig.…”

3d? excitation in slow Ne-Ar collisions

The impact parameter dependence of Ar L-shell excitation in Ne-Ar collisions has been studied at collision energies of 200, 400 and 700 keV. Experimental vacancy production rates have been obtained by observing Ar-L Auger electrons in coincidence with scattered ions. A theoretical analysis of the experimental data has been performed by assuming vacancy production in the quasimolecular 3do. orbital to be the dominant mechanism for Ar L-shell excitation. Probabilities have been calculated separately for 3 do-excitation via 3 dO-3 dg-3 do-rotational coupling and via direct coupling to the continuum. The data at large impact parameters (where the calculated contribution from direct ionization is negligibly small) can be understood solely in terms of rotationaUy induced 3 do-excitation. The enhancement of the vacancy production rate over the rotational-coupling contribution observed for smaller impact parameters is explained qualitatively by the onset of direct 3dg ionization. Total cross sections for Ar-L vacancy production have been determined experimentally for collision energies ranging from 70 to 700 keV, and have been analyzed also in terms of 3 do. excitation.
