Marshall for useful comments.Radiative corrections using third-order perturbation theory are considered in a theoretical calculation of the Zeeman effect. The corrections have been calculated for the states 2 3^P of helium, and found to be of the same order as other radiative corrections calculated by Anthony and Sebastian.engjournal articlehttp://dx.doi.org/10.1103/PhysRevA.56.3576http://journals.aps.org/open access535OpticsPhysicsAtomicMolecular & ChemicalÓptica (Física)2209.19 Óptica Física
