    "abstract": "The fine structure interval of P states in hydrogenlike systems can be\ndetermined theoretically with high precision, because the energy levels of P\nstates are only slightly influenced by the structure of the nucleus. Therefore\na measurement of the fine structure may serve as an excellent test of QED in\nbound systems or alternatively as a means of determining the fine structure\nconstant $\\alpha$ with very high precision. In this paper an improved analytic\ncalculation of higher-order binding corrections to the one-loop self energy of\n3P and 4P states in hydrogen-like systems with low nuclear charge number $Z$ is\npresented. A comparison of the analytic results to the extrapolated numerical\ndata for high $Z$ ions serves as an independent test of the analytic\nevaluation. New theoretical values for the Lamb shift of the P states and for\nthe fine structure splittings are given.",
