A method to measure neutron polarization using P-even asymmetry of γ-quantum emission in the neutron-nuclear interaction
2012
A new method to measure polarization of cold/thermal neutrons using P-even asymmetry in nuclear reactions induced by polarized neutrons is proposed. A scheme profiting from a large correlation of the neutron spin and the circular γ-quantum polarization in the reaction (n, γ) of polarized neutrons with nuclei is analyzed. This method could be used, for instance, to measure the neutron-beam polarization in experiments with frequently varying configuration. We show that high accuracy and reliability of measurements could be expected.
