A scintillation proportional counter with wavelength shifting fiber readout filled with Xe or Kr under a pressure of up to 20 atm is proposed for the low–background experiments on search for dark matter of the Universe and 2K–decay of Kr.

Selective exotat~on of Kr atoms at the surface of sohd Ar with synchrotron radlatton stimulates the desorptlon of excited Kr atoms (e g., Kr3P1) as well as the luminescence of Kr-type surface centers at hv = 9 998 eV (3P 1) and at hv = 9.881 eV (3P 2) The high-resolution luminescence spectra and the yield curves of the radiative decay channels have been measured. They are interpreted taking int...

The energies and dispersions of the image states and quantum well electronic states in layers of Xe and Kr on a Ag~111! substrate were determined by angle-resolved two-photon photoemission ~ARTPPE!. For Xe, we measured binding energies of unoccupied electronic states for 1–9 layers and their parallel dispersion out to 4 layers. We measured the binding energies for a monolayer of Kr and dispersi...

Experiments demonstrating the feasibility of Kr-edge MAD on frozen crystals as a routine method for structure determination are reported. Approximately 50% of protein crystals can be successfully derivatized by pressurization with the noble gases xenon or krypton. While Xe has produced many useful derivatives for MIR phasing over the last several years, the Xe edges (K edge = 34.6 keV, L(I) = 5...

In this paper, we use a statistical thermodynamic approach to quantify the efficiency with which clathrates on the surface of Titan trap noble gases. We consider different values of the Ar, Kr, Xe, CH4, C2H6 and N2 abundances in the gas phase that may be representative of Titan’s early atmosphere. We discuss the effect of the various parameters that are chosen to represent the interactions betw...

The ionization rates and subsequent electron dynamics for laser-induced plasma channels are measured for the noble gas series He, Ne, Ar, Kr, and Xe at 1.0 atm. The cw fluorescence emission increases superlinearly in the series from He to Xe in agreement with Ammosov-Delone-Krainov tunnel ionization calculations. The electron temperature after laser-induced plasma formation, measured by four-wa...

Hydrogen-bonded frameworks self-assembled from metal–nucleobase complexes and hexafluoro anions are reported by Wei Zhou, Zongbi Bao et al. in their Research Article (e202117609). Amino-rich ligands provide multiple H-bonding sites to stabilize the frameworks. In confined channels, electron-rich combined with electron-deficient purine rings generate a micro-electric field polarize lock Xe atoms...
