Abstract :
The large current of corona discharge in liquid Ar was measured as a function of tip voltage. Electric field in a gap is large enough to heat of electrons which are carriers of the current and their mobility depends on the field. Calculated electronic current is larger than that in the experiment. Capture of the electrons by attaching impurities are taken into account. The impurity concentration is estimated from the experimental data of corona current
