摘要：
The combined fine and hyperfine structure of the 2(3)P states in He-3 is calculated within the framework of nonrelativistic quantum electrodynamics. The calculation accounts for the effects of order m alpha(6) and increases the accuracy of theoretical predictions by an order of magnitude. The results obtained are in good agreement with recent spectroscopic measurements in He-3.
