Abstract
A complete calculation of relativistic and quantum electrodynamic effects to order on the energy of the state in helium is presented. The result, beyond the previously known radiative corrections, amounts to MHz, and significantly reduces the theoretical uncertainty. The improved theoretical predictions are compared to the best available experimental result for the state.
