Abstract
Constraint on spin-dependent and spin-independent Yukawa potential at atomic scale is developed. That covers constraints on a coupling constant of an additional photon and a pseudovector boson. The mass range considered is from to . The strongest constraint on a coupling constant is at the level of a few parts in (for ) and below one part in (for a pseudovector) corresponding to mass below . The constraints are derived from low-energy tests of quantum electrodynamics and are based on spectroscopic data on light hydrogenlike atoms and experiments with magnetic moments of leptons and light nuclei.
