Properties of ionizition chambers with parallel plane electrodes, filled with highly purified hexane are examined. At 26 deg C, the remanent current density (background) is 2.10/sup -//sup 1//sup 4/ amp/cm/sup 2/ when an electric field of 8.2 kv/cm is applied. A 12 millicurie source of Co/sup 6//sup 0/ is situated in the middle of one of the electrodes, which makes the ionization current a hundred times greater than the remanent current. The Jaffe theory can be applied for fields up to 20 kv/cm. Above this field value, an amplification effect is observed that can be compared to the multiplication process in gaseous fillings. The pulses produced hy 5.3 Mev alpha particles are shown in the region where this amplification effect exists. For electric fields from 25.6 kv/ cm to 65.6 kv/cm, the amplitudes of impulses are between 25 and 250 mu v and the rise times between 5 and 20 mu s. (auth) 1961). (In English). (UCRL-9411)
