Measurement of the Effective Thermal Cross Section of ~134Cs by Triple Neutron Capture Reaction

摘要

The effective thermal cross section (sigma_eff) of the ~134Cs(n,gamma(~135Cs raction was measured by the activation method and the gamma-ray spectroscopic method in order to obtain fundamental data for research on the transmutation of nuclear wastes. The effective thermal cross section of the reaction ~134Cs(n,gamma)~135Cs was found to be 140.6+-8.5 barns.
