  Direct observation of nonadiabatic transitions in Na+rare-gas differential optical collisions

  摘要：

  We study the dynamics in optical collisions of Na with Ne, Ar, Kr, and Xe in a differential scattering experiment. We report the observation of nonadiabatic transitions in the excited collisional quasimolecule based on measurements of the population ratio of the Na(3p)2P1/2 and 2P3/2 fine-structure levels. Comparison with theoretical results shows a generally very good agreement over the range of collision energies (0.01–0.3 eV) scanned in our experiment, using the best available potentials. For the heavier rare-gas systems a strong influence of the BΣ–AΠ crossing on the population ratios is observed. We further extract a universal function for the nonadiabatic transition probability for these systems. In the thermal energy range, our results are in good qualitative agreement with data from gas phase optical collision experiments.

  The absorption spectrum of the van der Waals molecule NaKr due to the transition X 2Σ→A2Π has been observed with high resolution using a tunable single-mode cw dye laser and producing the molecules by means of supersonic expansion. About 600 lines due to the most abundant Kr-isotope Kr84 have been analyzed. The spectroscopic parameters of molecular rotation, of fine structure splitting and of λ-type doubling have been obtained for the vibrational levels v′=10⋅⋅⋅14 of the A 2Π state and for the level v″=0 of the X 2Σ state. The experimental positions of the band origins of the vibrational transitions are in satisfactory agreement with the results of model potential calculations. The equilibrium distances of the X 2Σ and of the A 2Π state of NaKr84 have been determined to be 4.919(7) and 3.02(9) Å, respectively. For the well depth we obtain values of (69±4), (790±60), and (750±60) cm−1 for X 2Σ, A 2Π1/2, and A 2Π3/2, respectively.
