Abstract
It is shown that Lee's nonunique phase-shift parameters ${\ensuremath{\eta}}_{l}(\ensuremath{\kappa})$, determined from the experimental Fermi surfaces of Cu and the alkali metals, can be transformed into a unique set of parameters consisting of logarithmic derivatives ${L}_{l}$ at corresponding atomic radii ${S}_{l}$. The physical significance of these parameters is discussed and it is shown that they give direct information about the conduction electrons in the metal.
