Cyclotron masses, electronic specific heat, and Fermi velocities in copper

The electronic density of states on the Fermi surface of copper has been calculated starting from the cyclotron masses of Coleridge and Watts, and those of Koch, Stradling, and Kip. The comparison of the results with the experimental value of the electronic specific heat indicates that the first set of masses is more consistent with the current ideas of the Landau quasiparticle theory. Using these masses, the Fermi velocities at any point of the Fermi surface have also been calculated.
