摘要
We evaluate a number of systematic effects that are important for an experimental microwave measurement of the n = 2 S-to-P intervals in atomic hydrogen. The analysis is important both for reevaluating the best existing measurement [S. R. Lundeen and F. M. Pipkin, Phys. Rev. Lett. 46, 232 (1981)] of the 2S(1/2)-to-2P(1/2) Lamb shift and for a measurement that is ongoing in our laboratory. This work is part of a larger program to understand the several-standard-deviation discrepancies between various methods for determining the proton charge radius.
