Estimation of electron potential emission yield dependence on metal and ion parameters

Abstract

The paper discusses the dependence of γ-the coefficient of potential emission of electrons from metals on the work function ϕ and Fermi energy εF for metals and the ionization energy of ions Ei . It has been found that in the range 3ϕ <Ei<2(∊F+2ϕ) Deviations from this dependence exceeding 10% have been observed at Ei<3ϕ and at Ei > 2(∊F + ϕ) Theoretical estimates are in satisfactory agreement with experimental results.
