Abstract
Spectroscopy and dynamics of multielectron atomic system in a magnetic field is numerically investigated. It is presented a new quantum-mechanical approach to calculating the energies and widths of some states for the multi-electron atomic system in in a homogeneous magnetic field. The approach is based on the numerical difference solution of the Schrödinger equation, the model potential method and the operator perturbation theory formalism. As illustration, the data for energies of the electronic excited and ground state of the lithium atom in dependence upon the magnetic field strength are listed and compared with available theoretical results, obtained on the basis of alternative Hartree-Fock method.
