RT Journal Article T1 Radiative corrections in the Zeeman effect of 2 3^P states of helium A1 Gonzalo Fonrodona, Isabel A1 Santos, Emilio AB 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.
