✦ Synopsis

The relationship between the resonance integral (p) and the derivative of the overlap ktegral (s) is explored for an electron trapped in two equivalent centres separated by a distance R, tie interaction at each centre being assumed to be a superposition of screened and unscreened Coulomb potentials. It is shown that there exist particular values of' the parameters characterising the potential and of the distance R, for which the Linderberg relation p = (L/R) dS/dR b a satisfactory approximation.
