Classification: 2.1. | ||

Nature of problem:Prediction of Zeeman splittings using Breit-Pauli wave functions. | ||

Solution method:The electronic wave function for a state labeled gammaJM can be expanded in terms of LSJ coupled configuration state functions Psi(gammaJM) = Sigmai(ci Phi(gammaiLiSiJM)). The Lande g factor can then generally be calculated by summing the g factors between configuration state functions weighted by the product of the expansion coefficients. Using the Lande g factors the total interaction matrix is constructed. By diagonalizing the interaction matrix for different values of the magnetic field the positions of the magnetic sublevels are obtained. | ||

Restrictions:The complexity of the cases that can be handled is entirely determined by the MCHF atomic structure package [1] used for the generation of the electronic wave functions. | ||
