Photoelectric determination of V 0 values and electron ranges in some cryogenic liquids

Abstract

Conduction state energies V 0 were measured for liquid neon, argon, krypton, xenon, liquid nitrogen, liquid methane and ethane, and mixtures of methane and ethane by means of photo-effect on a metal electrode. A lower limit of V 0 for liquid hydrogen was estimated. From the dependence of the photocurrent on the electric field strength electron penetration ranges could be deduced.
