The calculations demonstrate the need to include relativistic corrections for a good representation of the Fermi surface. Self-consistent calculations are performed using various exchange-correlation potentials. The calculations indicate that Barth-Hedin-Janak exchange provides the best agreement with the experiment. Enhancement factors are also calculated using the BHJ exchange-correlation potential. These are compared with experimental results as well as with some of the available theoretical calculations.
