B-spline algorithm for magnetized multielectron atomic structures
Abstract
A B-spline algorithm has been developed to evaluate the electronic structure of multielectron atoms in a magnetic field. A generalized electron configuration concept, which is crucial to perform the current investigation, was introduced to solve Hartree-Fock equations. The wave functions for electron orbitals of the magnetized multielectron atom are expanded in terms of a B-spline basis in the radial direction and spherical harmonics in the angular direction. The developed algorithm has been applied to calculations of He in a magnetic field. Energy levels of magnetized He in the ground state are presented as a function of magnetic field strength with a range from zero up to 2.35×107T and compared with available theoretical data.
