Quantum electrodynamic calculation of the hyperfine structure of 3He
arXiv:1203.6840 · doi:10.1103/PhysRevA.85.042517
Abstract
The combined fine and hyperfine structure of the $2^3P$ states in $^3$He is calculated within the framework of nonrelativistic quantum electrodynamics. The calculation accounts for the effects of order $mα^6$ 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.
