An APW Calculation for Silver

Various “muffin tin” potentials have been examined, and a potential leading to a band structure and a Fermi surface in agreement with experiments has been found. This potential is based on relativistic Dirac‐Slater atomic wave functions. In the atomic calculations as well as in the crystal calculations inclusion of full Slater exchange led to the best results. Cyclotron masses, thermal effective mass, optical mass, drift velocities, and group velocities have been calculated.
