Reanalysis of the Eötvös experiment

The results of the experiment of Eotvos, Pekar and Fekete (1922), which compared the gravitational accelerations of various materials to the earth, are reexamined, in order to find evidence of a non-Newtonian coupling Delta V(r). It is found that the Eotvos-Pekar-Fekete data are sensitive to the com...

Zusammenfassung:The results of the experiment of Eotvos, Pekar and Fekete (1922), which compared the gravitational accelerations of various materials to the earth, are reexamined, in order to find evidence of a non-Newtonian coupling Delta V(r). It is found that the Eotvos-Pekar-Fekete data are sensitive to the composition of the materials used, (Magnalium-Pt, CuSO4-Cu in solution, and tallow-Cu). The existence of an intermediate range coupling to the baryon number or hypercharge of the materials was confirmed. (I.H.)
