Abstract

THE main point at issue occurs in the first paragraph. It is whether or not there is an abrupt potential change at the surface, whatever name it be called—contact potential or potential barrier. The original statement by Workman and Reynolds that the potential barrier is at the water-ice interface means in the ordinary use of language that the potential change, which may be more than 100 volts, is a complete discontinuity there, or at best is spread over a distance of a few molecular diameters, involving an electric force of millions of volts a centimetre. The expanded statement seems to imply much the same.
