Abstract

The neutron spin-orbit interaction, which results from the interaction of a moving neutron's magnetic dipole moment (MDM) with the atomic electric fields, induces a small rotation of the neutron's spin in one Bragg reflection. In our experiment neutrons undergo on the order of 100 successive Bragg reflections on the walls of a slot cut into a perfect silicon crystal to amplify the spin rotation. Here we report a measurement polarization rotation from multiple Bragg reflections. From these measurements, we determined the average atomic electric field sensed by the neutron during Bragg scattering from silicon.
