Abstract
Helicity dependence was observed for the resonance of the neutron radiative capture reaction of139La using a polarized neutron beam. The polarized neutron beam was produced by a dynamically polarized proton filter. The neutron polarization was about 70 % throughout the measurement. The preliminary result of the asymmetry in theγ-ray count was (9.5±1.2) %. Experiments were also carried out for98Mo,108Pd and129Xe. Such a large asymmetry as that found in139La was not observed in these nuclei.
