Observing pre-edgeK-shell resonances in Kr, Xe, andXeF2

EVALUATING Kr- AND Xe-DATA IN THE NAKHLITES AND ALHA

Results on nakhlite Martian meteorites and on ALHA84001 have led to a debate on the noble gas components contributing to the inventory of these meteorites and the ways to introduce them [1-7]. In a diagram Xe/Xe vs. Kr/Xe they fall off the mixing line Martian interior – Martian atmosphere tending towards lower Kr/Xe-ratios. This was discussed already in 1988 by [8], who suggested incorporation ...

Hyper-Rayleigh spectral intensities of gaseous Kr-Xe mixture.

Binary collision-induced hyper-Rayleigh (CIHR) spectra of Kr-Xe gaseous system are computed quantum mechanically and classically within the frequency range up to 380 cm(-1). The intensities are expressed in absolute units. The details of the theory developed for the CIHR spectra are given and the properties of the profiles as well as the depolarization ratio frequency dependence are discussed. ...

Observing atomic collapse resonances in artificial nuclei on graphene.

Relativistic quantum mechanics predicts that when the charge of a superheavy atomic nucleus surpasses a certain threshold, the resulting strong Coulomb field causes an unusual atomic collapse state; this state exhibits an electron wave function component that falls toward the nucleus, as well as a positron component that escapes to infinity. In graphene, where charge carriers behave as massless...

Enhanced High Harmonic Generation from Xe, Kr, and Ar in a Capillary Discharge

HXeI and HXeH in Ar, Kr, and Xe matrices: experiment and simulation.

Experimental and theoretical studies of HXeI and HXeH molecules in Ar, Kr, and Xe matrices are presented. HXeI exhibits the H-Xe stretching bands at 1238.0 and 1239.0 cm(-1) in Ar and Kr matrices, respectively, that are blue-shifted from the HXeI band observed in a Xe matrix (1193 cm(-1)) by 45 and 46 cm(-1). These shifts are larger than those observed previously for HXeCl (27 and 16 cm(-1)) an...
