“…Using this correction, the measured ion mobility in normal liquid helium in the temperature range from 2.17 to 4.2 K is fit quite well with the Ostermeier and Schwartz model [18]. The theoretical cluster radius in liquid xenon as a function of temperature can be determined by solving (13) with ( 14) using κ = 1.94 [22] and n s = 3.4 g cm −3 [23] for xenon as approximately constant, and P m , P s , σ lg and n l as a function of T from [20,24]. The results are plotted in figure 1.…”

The mobility of alkaline earth ions, Mg+, Ca+, Sr+ and Ba+, in liquid xenon is measured for the first time. The mobility of Tl+ is also determined for comparison with a measurement by other researchers. The Atkins cluster model for positive ions in non-polar liquids, based on the electrostriction effect, gives general agreement with the magnitude of the mobility values. This is some evidence that the positive ions form a snowball rather than a bubble structure in liquid xenon. However, the temperature dependence of the mobility does not match well with the Atkins theory, so there are still open theoretical questions on the nature of the environment of alkaline earth ions in liquid xenon. The lower mobility of Mg+ and Ba+ may be explained by a better size match to interstitial and substitutional sites, respectively, in solid Xe. These measurements are motivated by the development of a new technique to search for neutrino masses through 0νββ decay of 136Xe. A key component of one version of the proposed experiment is tagging of 136Ba+ daughter ions in liquid 136Xe by laser-induced fluorescence.

“…Like in Ref. 4, we used perturbation theory to calculate the energy corrections. The contribution of each term to the total energy shift is reported in Table III; the 2p exciton lies lower in energy than the 2s exciton by 0.01 eV compared to the experiment which suggests that the 2 p exciton lies higher in energy than the 2s exciton by 0.081Ϯ0.01 eV.…”

Excitation spectra of two-photon excited solid xenon have been obtained in the energy range of 8.4 to 11.1 eV. The measurements were performed at temperatures from 160 to 100 K. The even-parity ⌫(3/2) nϭ2, 3, and 4 Wannier excitons are observed in solid xenon. The nϭ2 and 3 excitons are shifted to higher energies relative to the energy of the corresponding odd-parity excitons by approximately 80 and 50 meV, respectively. In addition, the excitation spectrum revealed a previously unobserved series of excitons between 10.7 and 11 eV. These excitons form a Rydberg series and are possibly assignable as excitons at the X point of the Brillouin zone. The absorption linewidths ͑full width at half maximum͒ of the 2p, 3p, and 4p excitons are measured to be approximately 80, 52, and 22 meV, respectively. Several models are investigated in an attempt to explain the shift in energy between the s and p excitons in liquid and solid xenon.

“…66,67 As for problem (2) the FUV transitions have been studied for molecules in rare gas solid matrices, as liquids and as condensed gases. 68,69 For example, the dependence of density of rare-gas matrices and liquids on the transition energies and spectral width has been discussed. However, such studies for realistic systems with strong interactions like organic molecules in pure liquids have never been carried out.…”

Far-Ultraviolet Spectroscopy in the Solid and Liquid States: A Review

UV region'' is no longer appropriate for the 120-200 nm region because most recent spectrometers used in this region are not evacuated but instead incorporate a nitrogen purge. This review consists of eight parts: (1) introduction to FUV spectroscopy, (2) brief history of FUV spectroscopy, (3) development of new FUV spectrometers, (4) FUV studies of liquid water and aqueous solutions, (5) FUV spectra of organic molecules in the liquid states, (6) band assignments by quantum chemical calculations, (7) potential applications of FUV spectroscopy in liquid and solid states; and (8) future prospects of FUV spectroscopy.
