The complete mα6 contribution to the helium 2 3PJ energy

Show affiliations


A complete calculation of the mα6 contribution to the helium ionization energy of 2 3PJ states is presented. The result, beyond the previously known radiative corrections, amounts to 0.4046 MHz and significantly reduces theoretical uncertainties. The computational method is based on the effective Hamiltonian derived from relativistic quantum electrodynamic theory. The current status of theoretical predictions is summarized and a comparison with the latest experimental results is performed.
