An effective technique for computation of the electron density and spin magnetic moment in a ferromagnet, based on the relativistic Korringa - Kohn - Rostoker method, is developed and realized. The calculation formulae are derived using the Hellmann

Using the Hellmann-Feynman theorem an expression for the electron effective mass in crystal is derived. Calculations are carried out at some points of Fermi-surface cross-section of vanadium by the plane z = 0. The comparison with the data of numeric

Matrix elements of momentum and of gradient of the potential for electronic states in solids are calculated by the Green's function method. Their absolute identity is shown if the integral over the elementary cell volume is correctly reduced to integ

An analog of Green's theorem for the Dirac operator is obtained, which allows to reduce the integration over the outer part of the Wigner-Seitz cell volume to that through the muffin-tin sphere surface. Within the relativistic variant of the Green's

Using the Hellman-Feynman theorem and the perturbation theory for the matrix, an expression for the electron velocity in crystals is derived. Calculations are carried out on a mesh of 55 points in 1/48 th of the b.c.c. Brillouin zone for six energy b

The exact formula for the calculation of the electron velocity in the relativistic case is obtained by using the Hellman-Feynman theorem and the perturbation theory for the matrices. The computation is performed along the symmetrical lines of 1/48th
