Measurement of cross section of the Mo-98(n,gamma) Mo-99 reaction using monochromatic thermal neutrons

摘要

The cross sections of the reaction Mo-98(n, gamma) Mo-99 at neutron energies of 0.0334 eV and 0.0536 eV were measured for the first time using the activation technique, and the resulting values of 116 +/- 7mb and 91 +/- 5mb, respectively, are in good agreement with the JENDL-4 and ENDF/B-VII data files. Those measured values were extrapolated to the energy 0.0253 eV assuming 1/v dependence in the thermal region and the results were compared with the integrally measured values reported in the literature. The new data are thus useful to check the evaluated excitation function.
