A Search for non-Newtonian force in a precision measurement of the scattering of slow neutrons in Xenon gas

摘要

An experimental search for non-newtonian, gravity-like force in a precisionmeasurement of the scattering of slow neutrons in Xenon gas is proposed. Apreliminary experiment with small statistics of 25 hours irradiation time wasperformed and the observed scattering distribution is consistent with theexpectation with no additional forces. A 95% CL limit on the coupling strengthfor a hypothetical force of 1 nm interaction range was evaluated to be2*10^-15. The expected sensitivity for a planned high statistics runs isdiscussed.
