Abstract
We describe a nonperturbative (in Zalpha) numerical evaluation of the one-photon electron self-energy for 3P1/2, 3P3/2, 4P1/2, and 4P3/2 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 Zalpha and lead to improved theoretical predictions for the self-energy shift of these states.
