摘要：

It is shown that the function G(q), which contains the exchange and correlation corrections in the theory of dielectric screening, has a decisive effect on the force constants of simple metals. Especially for a substitutional alloy of A and B atoms, the differences between the A-A, A-B and B-B force constants depend crucially on the choice of the function G(q). This is demonstrated for the Rb1-cKc system and comparisons with neutron scattering experiments are made.
