Gamma-ray production data of N, Na, Al, Si, Ca, Ti, Fe, Ni and Cu in JENDL-3 have been tested by comparing the calculated γ-ray spectra with the experimental ones measured at ORNL. As to γ-rays arising from thermal neutron capture, structures observed in the measured spectrum could not be reproduced for most cases with the test version of JENDL-3 (JENDL-3T) whose evaluation was made mainly on the basis of theoretical calculation, while they were reproduced well with ENDF/B-IV. As to γ-rays arising from fast neutron reactions, on the other hand, JENDL-3T reproduced the measured spectra fairly well except for Ca, Fe and Ti, where JENDL-3T gave too high values in the γ-ray spectra between 4 and 6 MeV. Considering the results of the benchmark tests, the γ-ray spectra arising from the thermal neutron capture were reevaluated and the modified data were adopted in the final version of JENDL-3.
