The present status of the JENDL high-energy file is reported. The recent version (referred to as JENDL/HE-2007) contains neutron and proton cross section data for energies up to 3 GeV for 107 nuclides over the wide mass range from H to Am. The newly evaluated data for 41 nuclides have been added to the first version (JENDL/HE-2004) along with some revisions. The JENDL/HE-2007 includes neutron total cross sections, nucleon elastic scattering cross sections and angular distributions, nonelastic cross sections, production cross sections and double-differential cross sections of secondary light particles (n, p, d, t, 3 He, α, and π) and gamma-rays, isotope production cross sections, and fission cross sections in the ENDF-6 format. The evaluations were performed on the basis of experimental data, nuclear model calculations, and systematics based on measurements. The evaluated cross sections are compared with available experimental data and the other evaluations. Some results of benchmark tests with MCNPX codes are shown.

The JENDL Dosimetry File, which contains 67 dosimetry reactions, has been revised by the Dosimetry Integral Test Working Group of the Japanese Nuclear Data Committee. Thirty-one cross sections and their covariance data were simultaneously evaluated mainly through a generalized least-squares code using the experimental data in EXFOR. In order to confirm the reliability of the present revised data, integral tests have been carried out by comparing the calculated spectrum-averaged cross sections with the measured ones in fission neutron fields, fast/thermal reactor neutron fields, D-T and D-Li fusion-like neutron fields. In most of the dosimetry cross sections, it has been found that the ratios of calculated to experimental results on their integral tests show reasonable agreement within predicted uncertainty, while unreasonable discrepancies are still observed in some revised JENDL dosimetry cross sections.
