Abstract
An experimental search for new forces coupling to nuclear isospin with a range of ≥3 m was conducted using a torsion balance driven in resonance by a set of masses configured to generate a nearly pure isospin source field. The strength of any such coupling ξ in units of gravity per atomic mass unit is found to be bounded by -2.3×10-4≤ξ≤+2.7×10-5, where the positive sign represents an attractive force between like isospin charges.
