New analytical expressions for the surface ionization, ϕ(0), and the amplitude of the ionization distribution, ϕ(ρ z ), in the surface γ 0 , are derived which take into account physical reality. Values of these parameters are obtained using these expressions and compared with previous models and experimental determinations. The proposed expressions show very good agreement with measured values.
