Hamiltonian Operator and Eigenvalue EquationThe Dirac Hamiltonian operator [Dirac (1928a, b)] for a one-electron atomic system is.where c is the velocity of light, . is the momentum operator (. = -i∇), and the operators α and β are defined by.I is the two-dimensional unit matrix and the σ. denote the Pauli matrices.V(.)is the central potential and . is the position vector of the electron.

Transformation of Operators to Tensor FormThe evaluation of the matrix elements of the Hamiltonian operator through the use of the reduced matrix elements formulation presented in the preceding Chapter requires that its terms be transformed into tensor form (see Section 4.2).

Numerical ResultsThe formulation presented in this work was implemented in a computer program [Fraga .. (1987)], used in some test calculations. Some of the corresponding results are presented here in order to illustrate the difficulties to be faced and the quality of the results.
