Abstract

The effective Madelung energy of a transition leading to the generalization of the law of Hilsch and Pohl is defined. A very simple empirical method is given for the determination of the effective Madelung energy of a transition in crystals. The method enables to estimate the position of the maxima for bands α, β, U(H^−^), I^−^, A(Tl^+^), B(Tl^+^), C(Tl^+^), D(Tl^+^), C(Ag^−^), etc. Also, valuable indications are obtained regarding the nature of transition and the mode of participation of the lattice ions in the transition.
