Electron work function of sodium: The current state of researches

摘要

The given is the review of the basic result of experimental investigations of the electron work function of sodium. It has been shown that (i) existing data are a few and obtained in narrow temperature limits, (ii) electron work function of sodium at negative temperatures is reported in just several papers, (iii) the temperature dependence of electron work function does not reveal any noticeable breaks neither discontinuities in the area of phase transition “solid-liquid”.
