Abstract
Results from two recent ‘‘fifth-force’’ experiments disagree when analyzed in terms of a single baryonic interaction. We consider an interaction coupling to =B cos+L sin where has a value that could explain our null Cu-Be data while preserving Thieberger’s positive Cu-O result. (B and L are baryon and lepton number, respectively.) We present new Al-Be data that rule out this possibility except for a narrow region around ≊-63° (∝, the third component of isospin), where the of terrestrial sources vanishes.
