Quantum electrodynamic calculation of the hyperfine structure of 3He

Abstract

The combined fine and hyperfine structure of the $2^{3}P$ states in ${}^3$He 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 ${}^3$He.
