TL;DR: JENDL-3.2 as discussed by the authors is the most recent version of JENDL 3.1.2, which is based on the feedback information of various benchmark tests and includes the resonance parameters, capture and inelastic scattering cross sections, and fission spectra.

TL;DR: In this paper, a new parametrization of the Fermi-Gas model description of nuclear level densities at excitation energies corresponding to the neutron binding energy is presented.

TL;DR: In this paper, a least square method was applied to selected absolute and relative measurements on the fission cross sections of 233U, 235U, 238U, 239Pu, 240Pu and 241Pu was carried out for the evaluated nuclear data library JENDL-3.3.

TL;DR: The Japanese Evaluated Nuclear Data Library (JENDL-3.3) as discussed by the authors is the third version of the JENDL.3. The objectives of the current release were to fix several problems which have been reported for the previous version, to improve the accuracy of the data, and to evaluate covariances for the important nuclides.

TL;DR: In this paper, Covariances of neutron nuclear data have been estimated for 16 nuclides contained in JENDL-3.2 using least-squares methods, and the covariance file is processed by a system which is used for the adjustment of group cross sections.
