Abstract
Application of a direct general method for calculating the magnetic field gen-
erated by two electrons bound in angular momentum eigenstates is presented,
illustrated and applied to the ground states of the tripositive ions Pr“ and
V3+. The ground state wave functions are written as a four components
spinor and the operators for the orbital current and spin densities as a 4 x 4
matrices. Analytical expressions for the expectation values of these opera-
tors are presented by making use of hydrogenic wave function. The resulttent
expressions of the current densities are substituted in the components of the
magnetic field which gives unexpected results.
