Evaluated neutron cross sections for zirconium and hafnium. Final report

Neutron cross sections of the elements zirconium and hafnium have been evaluated. These evaluations have been based on available experimental data supplemented by earlier theoretical nuclear model analyses. The evaluations include thermal cross sections and resolved resonance parameters for the naturally occurring isotopes of zirconium and hafnium. Above the resonance range, elemental point cross sections and secondary neutron energy and angular distributions are provided. All data have been prepared in the ENDF/B format for inclusion in the ENDF/B-V library
