Abstract

We describe a nonperturbative (in Z\ensuremathα) numerical evaluation of the one-photon electron self-energy for 3P_1∕2, 3P_3∕2, 4P_1∕2, and 4P_3∕2 states in hydrogenlike atomic systems with charge numbers Z=1 to 5. The numerical results are found to be in agreement with known terms in the expansion of the self-energy in powers of Z\ensuremathα and lead to improved theoretical predictions for the self-energy shift of these states.
