Abstract

In the central potential approximation, the first and second derivative of the two‐body potential for metals in the atom positions can be calculated by inverting the eigenvalue equations for the phonons. The potential is obtained from a straightforward integration procedure. Explicit results for Na are reported, which fully reproduce the experimental phonon spectrum.
