Evaluation of neutron nuclear data for Z > 88 minor nuclides

Neutron nuclear data for 15 minor nuclides (Z > 88) have been evaluated in the energy range of 10-5 eV∼20 MeV. Since only few experimental data are available, the present evaluation was mainly based on the systematics of the data from neighboring nuclides and also optical and statistical model calculations. The evaluations have been carried out for neutron cross sections of total, elastic scattering, inelastic scattering, (n,2n), (n,3n), (n,4n), fission and capture reactions. In addition, angular and energy distributions of the emitted neutrons and average number of the emitted neutrons per fission were also evaluated. The results were compiled in the ENDF/B-V format and stored in the JENDL-3. (author)
