Abstract

A simple model is proposed to account for the temperature dependence of the current from a field emitter at constant potential in He II. Our experimental data suggest that a new conduction mechanism, for which an effective mobility mu = (8.0 +/- 0.4) x 10^-3 cm^2 V^-l s^-2 can be defined, is being obscrvcd below 0.5 K.
