Abstract
We generate two muffin-tin potentials for technetium using Slater exchange and calculate the Fermi energies and Fermi surfaces very accurately using the constant-energy-search Korringa-Kohn-Rostoker method. An explanation for experimental de Haas--van Alphen frequencies that were not previously understood is proposed. The bare-band theory contribution to the low-temperature specific heat is ..gamma../sub 0/ = 2.12 mJ/mol K/sup 2/ for the better potential. We demonstrate the feasibility of using the methods outlined in this paper for carrying out highly detailed calculations on hcp metals.
