Precise isotope shift spectroscopy in various atomic systems can provide a sensitive tool to constrain new physics, in particular new physics that couples to electrons and neutrons. I will present an analysis for estimating the reach of such measurements in the framework of effective field theory and various benchmark models for SM extensions: color neutral vector resonances, leptoquarks and the 750GeV scalar diphoton resonance. Furthermore I will also provide a comparison with the reach of the LHC, e+e− colliders and g−2 of the electron. Isotope shift spectroscopy can compete and possibly even improve the sensitivity to probe a broad variety of Standard Model extensions.
