“…22 -26 ,30-33,53 It was found that the ratio alb is nearly constant within one measuring cycle (20h). On a long time scale, however, alb drifts within 0.5 <alb< 1.5 (15) due to surface effects on the first dynode of DI under the pointed (50 fLm diameter· collimator) bombardment by XUV photons and metastables. The geometric mean of the bounds in Eq.…”

Rotationally inelastic transitions between the finestructure levels of the 3Σ− g electronic ground state of O2 J. Chem. Phys. 81, 2678 (1984); 10.1063/1.447977 Semiclassical calculations of cross sections for finestructure transitions in Rb (62P) and Cs (82P) colliding with rare gas atoms The emission of XUV photons from collision-induced fine~structure transitions Ne* e P O ,2)+R-+Ne*(1,3p l ) +R-+NeeS) +R+hv(74 nm) has been measured for R=He, Ne, Ar, and KrctS) in a beam-cell experiment. The metastable Ne* velocity ranges from 550 to 1600 m/s. No emission was found for Ne*ep o ) +R. An appropriate detector system enables the determination of absolute 3 P 2 .... 3 PI transition cross sections. The results of Ne*e P 2 ) + He and Ne are compared with theoretical calculations.

“…potentials, at intermediate or large internuclear distances [5]. From a theoretical point of view, a comparison of Ne2 and Ar2 systems has now become possible [8], as ab initio calculations have recently been performed on the argon dimer [6]. It was therefore interesting to undertake differential measurements of metastable Ar(3p5 4s, ~Po.2) on Ar(2p6, ISO) collisions.…”

Adiabatic potential surfaces have been computed ab initio for molecular states dissociating into Ne* (2p 53s,1,3P)+H2(1Σ+g). The distance R between Ne* and H2 ranges from 5 up to 50 a0. The distance r between H atoms is kept constant, equal to its equilibrium value (1.4 a0). The interaction with the electronic continuum is ignored. Potentials, including spin–orbit interaction, are fitted to analytic forms. Specific molecular properties of the system are discussed.
