Abstract
This program calculates the matrix elements of orthogonal operators for d^Nconfigurations. These operators are used to describe the perturbing effects of electrostatic, magnetic and crossed magnetic-electrostatic interactions on an atomic configuration. The reason for using orthogonal operators is that the mean errors of the parameters, which are associated with these matrices, are smaller than those of the conventional type of parameters. Whereas some of the matrix elements were available ...

Nature of problem
The perturbing effects of electrostatic, magnetic and crossed magnetic- electrostatic interactions on an atomic configuration can be taken into account by a complete set of orthogonal operators. The parameters associated with such operators can be extracted from the observed energy levels, and have smaller mean errors than conventional (non-orthogonal) parameters sets if determined by least squares fitting.
