Abstract. We report new measurements of the near infrared (NIR) Xe * 2 excimer fluorescence in an electronbeam-excited Ar (90%)-Xe (10 %) mixture at room temperature. Previous measurements up to a density N ≈ 2 × 10 26 m −3 discovered a broad excimer fluorescence band at ≈ 7800 cm −1 , whose center is redshifted by increasing N (A. F. Borghesani, G. Bressi, G. Carugno, E. Conti, and D. Iannuzzi, J. Chem. Phys., 115, 6042 (2001) [1]). The shift has been explained by assuming that the energy of the optical active electron in the molecule is shifted by the density-dependent Fermi shift and by accounting for the solvation effect due to the environment. We have extended the density range up to N ≈ 6 × 10 26 m −3 , confirming the previous measurements and extending the validity of the interpretative model. A detailed analysis of the width of the fluorescence band gives a value of 2.85 nm for the size of the investigated excimer state. Such a large value lends credence to the validity of the proposed explanation of the experimental findings.

“…23 More recent measurements of Alford 9 favor an even larger value ͑10.1Ϯ4.5͒ϫ10 Ϫ11 cm 3 /s and ͑6.7Ϯ4͒ϫ10 Ϫ11 cm 3 /s for the reverse process. For high enough xenon pressure, the reverse transfer from 6p͓1/2͔ 1 would couple the concentrations in the two states, and they would have an effective radiative lifetime of ϳ100 ns.…”

A new, simple method for the generation of Xe(6s[3/2]1) and Xe(6s′[1/2]1) atoms is described. The method involves resonant two-photon excitation of Xe(6p[1/2]0 and 6p′[3/2]2) states followed by amplified spontaneous emission (ASE) to the Xe(6s[3/2]1 and 6s′[1/2]1) states. The vacuum ultraviolet transitions, Xe(6s[3/2]1→5p6(1S0)) at 147 nm and Xe(6s′[1/2]1→5p6(1S0)) at 129.6 nm, were used to monitor the time dependence of the resonance state atom concentrations. The quenching rate constants of these resonance atoms with ten molecules were measured at 300 K. The quenching cross-sections of the Xe(6s and 6s′) resonance atoms are compared to the cross-sections of the metastable Xe(6s[3/2]2) atoms and Xe(6p[3/2]2) atoms. The correlation between quenching cross-sections and photoabsorption cross-section of the molecules predicted by the resonance dipole–dipole energy transfer model is discussed. The applicability of the two-photon driven ASE method for the generation of other resonance state atoms is considered.

For technical reasons the number of authors shown on this cover page is limited to 10 maximum. Using crossed beams of metastable rare gas atoms Rg*(ms 3P2, 3Po) (Rg=Ne, Ar, Kr, Xe) and ground state sodium atoms Na(3s 2S1/2), we have measured the energy spectra of electrons released in the respective Penning ionization processes at thermal collision energies. For Rg*(3P2)+Na(3s), the spectra are quite similar for the different rare gases, both in width and shape; they reflect attractive interactions in the entrance channel with well depths D* [meV] decreasing slowly from R g = N e to Xe as follows: 676(18); 602(23); 565(26); 555(30). For Rg*(3~)+Na(3s), the spectra vary strongly with the rare gas, indicating a change in the character of the interaction from van der Waals type attraction (Ne) to chemical binding for Kr and Xe with well depths D* [meV] of: 51(I9); 107(25); 432(30); 530(50). These findings are explained through model calculations of the respective potential curves, in which the exchange and the spin orbit interaction in the excited rare gas and the molecular interaction between the two valence s-electrons in terms of suitably chosen singlet and triplet potentials are taken into account. These calculations also explain qualitatively the experimental finding that the ratios q2/qo of the ionization cross sections for Rg* (3P2)+Na and Rg* (3Po)+ Na vary strongly with the rare gas fromNe to Xe as follows: 15.8(3.2); 2.6(4); 1.4(2); 1.6(4).
