Abstract

A constraint on a long-range spin-dependent interaction α^′′(\bf s₁⋅\bf s₂) \rm e^-λr/r, which can be induced by a pseudovector light boson, is presented. We study theoretical and experimental data on a specific difference 8× E_{\rm hfs}(2s)-E_{\rm hfs}(1s) for light two-body atoms. The spin-dependent coupling constant α^′′ of electron-nucleus interaction in hydrogen, deuterium and helium-3 ion is constrained at the level below a part in 10¹⁶. The derived constraints are related to the range of masses below 4 \rm keV/c².
