“…Recent and accurate measurements of mobility in Ne [4,5] and Ar [10,11] have put into evidence that the different behavior of the mobility in different gases can be rationalized into an unified picture, where all the multiple scattering effects are taken into account in a heuristic way. A model (henceforth known as the BSL model) has been developed that incorporates all features of the several models proposed to interpret the different density effects and merges the several multiple scattering effects into the single scattering picture of kinetic theory [10].…”

Electron mobility maximum in dense argon gas at low temperature

Journal of Electrostatics

2001

We report measurements of excess electron mobility in dense Argon gas at the two temperatures T = 152.15 and 162.30 K, fairly close to the critical one (T c = 150.7 K), as a function of the gas density N up to 14 atoms·nm −3 (N c = 8.08 atoms·nm −3 ). For the first time a maximum of the zero-field density-normalized mobility µ 0 N has been observed at the same density where it was detected in liquid Argon under saturated vapor pressure conditions. The existence of the µ 0 N maximum in the liquid is commonly attributed to electrons scattering off longwavelength collective modes of the fluid, while for the low-density gas a densitymodified kinetic model is valid. The presence of the µ 0 N maximum also in the gas phase raises therefore the question whether the single scattering picture valid in the gas is valid even at liquid densities.

“…The mobility in the dense gas shows a very pronounced peak at the very same density, at which a similar maximum is observed in liquid Ar at coexistence [31]. The peak in the gas can be somehow related to the RT minimum in the cross section [12], thus indicating that the RT minimum is [8] and for T = 151.5K (closed dots) [12].…”

Electron and ion transport in dense rare gases

IEEE Trans. Dielect. Electr. Insul.

2006

A review of the research on electron and ion transport in dense rare gases is presented. The investigation of the transport properties of electrons in dense rare gases aims at understanding the dynamics and energetics of electron states in a dense medium and at elucidating how changes of the environment influence their nature and scattering properties. The quantum nature of electrons couples them to the environment is such a way to produce a density-dependent shift of their energy that is the key to rationalize the observed phenomena. P.A.C
