Electron mobility and localization effects in high-density Ne gas

Effect of CH4 addition on excess electron mobility in liquid Kr

“…In this model, the many-body and multiple scattering effects due to the combined effect of short interatomic distances and large electron wavelength are embodied in the effective cross sections. This dressing of the scattering cross section due to multiple scattering effects is also at the base of the heuristic kinetic model, developed for the successful description of the electron mobility in dense noble gases 30,31,32,33 .…”

SIGN – A Gaseous-Neon-Based Underground Physics Detector

“…X=He, Ar, Xe, CH 4 ) mixtures can be operated in proportional mode (both charge and light) with excellent resolution. Studies have been limited to pressures of 100 bar, but electron mobility would allow operation at >300 bar [5].…”

Electron and ion transport in dense rare gases

“…In Figure 2 experimental results obtained for the zero-field densitynormalized mobility µ 0 N in He, Ne, Ar, and Xe are shown [8,9,10,13,14]. Constant lines in the picture indicate the predictions of kinetic theory that are strongly violated in real experiments.…”

“…In this way, the temperature T is not density N for He (squares) [9], Ne (triangles) [10], Ar (closed dots) [11,12], Xe (open dots) [13]. The constant lines are the prediction of kinetic theory.…”

“…Although the dynamics of bubble formation is not completely understood yet [28,29], the very simple quantum mechanical model of a particle in a spherically symmetric square box can grasp the essential physical features of localization [9,10].…”
