摘要：

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 in units of gravity per atomic mass unit is found to be bounded by -2.3×10-4+2.7×10-5, where the positive sign represents an attractive force between like isospin charges. © 1990 The American Physical Society.
