Motion of electrons in liquid xenon: Evidence for non-Boltzmann transport.

Abstract

This letter reports the Hall mobility of electrons injected into liquid xenon whose thermodynamic state is varied along the liquid-vapor coexistence line from the triple point to 275 K. Contrary to what would be expected from transport theory, when ${\mathrm{\ensuremath{\omega}}}_{\mathit{c}}$\ensuremath{\tau}1, the Hall angle is not a linear function of the magnetic field. This is particularly important near the mobility maximum and is interpreted as arising from interference effects. Their importance is a consequence of the fact that at the mobility maximum, the electron-phonon interaction is zero while elastic scattering by large density fluctuations persists.
