Abstract
- Agreement between theoretical calculations of atomic structure and spectroscopic measurements is used to constrain possible contribution of exotic spin-dependent interactions between electrons to the energy differences between states in helium-4. In particular, constraints on dipole-dipole interactions associated with the exchange of pseudoscalar bosons (such as axions or axion-like particles) with masses ${10}^{\ensuremath{-}2}\ensuremath{\lesssim}m\ensuremath{\lesssim}{10}^{4}\mathrm{eV}$ are improved by a factor of $\ensuremath{\sim}100$. The first atomic-scale constraints on several exotic velocity-dependent dipole-dipole interactions are established as well.
