Search for anomalous spin-dependent forces with a polarized-mass torsion pendulum

The existence of hypothetical anomalous spin-dependent forces is investigated using spin-polarized Dy6Fe23 masses acting on ones of unpolarized copper in a dynamic-mode torsion pendulum. An upper limit is provided for the strength of an anomalous interaction of the dipole- monopole form at ranges fr...

Zusammenfassung:The existence of hypothetical anomalous spin-dependent forces is investigated using spin-polarized Dy6Fe23 masses acting on ones of unpolarized copper in a dynamic-mode torsion pendulum. An upper limit is provided for the strength of an anomalous interaction of the dipole- monopole form at ranges from 1 to 100 cm. (P.D.)
