Times Cited Count:23 Percentile:82.08(Nuclear Science & Technology)The neutron capture cross section of Np-237 has been measured in the energy range of 0.02 eV - 100 eV. For the first time, the capture cross section of Np-237 was measured using the total energy -ray detector. The results have been compared with evaluated nuclear data libraries.

The neutron capture cross section of Np-237 has been measured relative to the B-10(n,alpha)Li-7 cross section in the energy range from 0.02 to 100 eV. The measurements were carried out by the time-of-flight method using the 8.54 liters BGO scintillator as a 4-pi capture ray detector and the 46 MeV Linac as a pulsed neutron source. The results of present measurements have been compared with experimental data of other authors and evaluated data.

The JENDL Dosimetry File 99 (JENDL/D-99) has been prepared for determinations of neutron flux/fluence and energy spectrum at specific neutron fields. This file contains data for 67 reactions with 47 nuclides. Cross sections for 33 major dosimetry reactions and their covariance data were simultaneously generated and the other 34 reaction data were mainly adopted from the first version, JENDL/D-91. The GMA code was mainly used for most of the evaluation procedures by referring the basic experimental data in EXFOR. The resultant data are given in the neutron energy region below 20 MeV in both of point-wise and group-wise files in the ENDF-6 format. In order to confirm reliability of the data, several integral tests have been carried out: comparison with the data in IRDF-90V2 and average cross sections measured in fission neutron fields, fast/thermal reactor spectra, DT neutron fields and Li(d,n) neutron fields. The contents of JENDL/D-99 and the results of the integral tests are described in this report. All of the dosimetry cross sections are shown in a graphical form in the Appendix.
