Fermi surfaces, similar in shape to that proposed for copper by Pippard, have been computed which fit Shoenberg’s experimental measurements of the de Haas-van Alphen effect in copper, silver and gold. It is shown that these are reasonably consistent with other experimental results, particularly the anomalous skin measurements of Pippard and Morton, although the shapes of the surfaces are markedly different in detail from the surfaces proposed by Pippard and Morton. Consideration has been given to using the cyclotron resonance data of Kip, Langenberg & Moore to deduce electron velocities, but without success.
