RELATIVISTIC EFFECTS IN HEAVY ELEMENTS
Relativistic effects upon the virial theorem and equation of state derived from variational calculations are described. In particular, it is shown that what is required in the calculation of the equation of state is the change in the sum of the one electron energies with Wigner-Seitz radius. Methods of obtaining the one electron energies are described and the differences between them explained. Various examples of the importance of relativistic effects are given: (1) the changes in the volumes of the elemental metals; (2) The difference between the volumes of the alpha and delta phases of Pu metal; (3) orbital magnetism in energy bands; (4) magnetic anisotropy in narrow band materials; (5) possible new semi- conductors.
