Motion of electrons in a classical liquid: injected electron Hall mobility in liquid neopentane along the liquid-vapor coexistence line between the triple and the critical point

Results of measurements of the Hall mobility of electrons injected in liquid neopentane along the liquid-gas coexistence curve between a few degrees above the triple point and the critical point are reported. The Hall mobility was measured by the Redfield technique. The time-of-flight mobility (TOF) was measured on the same sample over the same range in temperatures, and it is in good agreement with results published previously. The Hall mobility was found to differ significantly from the TOF.
