Abstract :
Fast and slow electron current signals in N2/Ar liquid mixtures have been observed. From the fast signal, the drift velocity and life time of delocalized electrons in the liquid with N2 molar fractions X=N2/(N2+Ar) below 20 mol% were obtained for field strengths E between 5 and 45 kV/cm. The mobility for delocalized electrons in the liquids was shown to decrease exponentially with X as indicated in a previous paper. However, the mobility for localized electrons was shown to increase with increasing X, but only slightly around the N2 liquid value
