Abstract

Improved theoretical predictions for the fine-structure splitting of

2^{3} P_{J}

levels in helium are obtained by the calculation of contributions of order

α^{5} Ry

. New results for transition frequencies

ν_{01} = 29 616 943.01 (17) kHz

and

ν_{12} = 2 291 161.13 (30) kHz

disagree significantly with the experimental values, indicating an outstanding problem in bound state QED.
