Abstract

Sidereal and daily modulations have been searched for in the decay of free polarized neutrons. A sample of about 3 × 108 decay electrons distributed over a three month long data taking period were analyzed. Independent upper limits could be deduced for the coupling of the neutron spin and the electron momentum to an external field postulated as an exotic admixture to the weak interaction dominating in neutron decay.status: publishe
