Wave functions and energy eigenvalues for potassium are calculated with the MAPW method using a nonlocal screened exchange potential. From the results obtained for several symmetry directions, the Fermi energy, the Fermi surface, its extremal cross‐sections, different masses, and the contribution of conduction electrons to the Knight shift are determined and related to experimental data.
