Measurement of electron mobility in liquid and gaseous argon at low electric field strengths and in the critical region
The mobility of excess electrons in argon has been determined from drift time measurements using the pulse-shape method. The excess electrons were generated by pulsed emission from a photocathode. The measurements were performed in liquid argon in the temperature range T/sub c/-35 K >
