Production of polarized neutrons by magnetic bremsstrahlung γ-rays

Circularly polarized magnetic bremsstrahlung (“synchrotron”) γ-radiation of ultrarelativistic electrons is suggested to be used to produce polarized pulsed neutrons by photonuclear reactions on light nuclei with a single valence neutron in the p-shell. The polarization, spectral and integral characteristics of photoneutrons have been determined by multigroup calculations for 9Be that is distinguished by an anomalously low neutron binding energy.
