This paper reviews the experimental activities since 1979 for the study of the spin polarization of photoelectrons emitted by atoms and molecules exposed to VUV radiation. Two series of studies have been performed: First, using unpolarized and linearly polarized radiation the photoionization of the rare gases Ar, Kr, and Xe has been studied in an angle-, energy-, and spin-resolved photoemission...

We discuss the present status and reliability of theoretical predictions of noble-gas hydride molecules. It is shown that the single-reference MP2 calculations can produce a rather inaccurate energy diagram for the formation of noble-gas hydrides, and this may mislead the theoretical predictions. We suggest that the computational dissociation energy of the HY precursors should always be compare...

Second dielectric virial coefficients BZ(T) of the rare gases Ne, Ar, Kr, and Xe are calculated in a broad range of temperature using accurate HFD-type interatomic interaction potentials and available information on the trace of the pair polarizability Aa. It is shown that the experimentally determined temperature-variation of BC(T) cannot be reproduced by existing theories. However, it is obse...

We have measured the far-field angular distributions of high harmonics (orders 11—41) generated by a 1-p,m, 1-ps laser pulse [(0.3—3)X 10 W/cm ] in low-density Ar, Kr, and Xe targets (~ 1 Torr, 1-mm thick). The far-field harmonic distributions show a narrow central structure surrounded by broad wings that contain approximately 75% of the harmonic energy. Low-density targets and f/70 focusing we...

A method is described for estimating solubility by fitting both solute and solvent properties in a single equation. The method is illustrated by examining the solubilities of five rare gases (He, Ne, Ar, Kr, Xe) and five 6permanent7 gases (O2, N2, CH4, CF4, SF6) in either n-alkane (C5H12 to C16H34) or alkan-1-ol (CH3OH to C11H23OH) solvents. Generally, the correlation (R2) values of the fits ac...

We present applications of extreme ultraviolet (XUV) single-order laser harmonics to gas-phase ultrafast photoelectron spectroscopy. Ultrashort XUV pulses at 80 nm are obtained as the 5th order harmonics of the fundamental laser at 400 nm by using Xe or Kr as the nonlinear medium and separated from other harmonic orders by using an indium foil. The single-order laser harmonics is applied for re...

Introduction Safe operation of a nuclear reactor depends to a large extent on the behaviour of different fission products generated within the fuel. While most of the fission products settle down as dissolved state in the fuel matrix or as separate phases, the gaseous products, xenon(Xe), and krypton(Kr), and the volatile products, iodine(I), tellurium(Te), cesium(Cs), and rubidium(Rb), underg...
