New Evaluation of the 99Tc Neutron-Induced Cross Sections for the ENDF/B-VII.0 Library

Neutron-induced cross sections for 99 Tc were evaluated from 10 −5 eV to 20 MeV for the U.S. ENDF/B-VII.0 library released in December 2006. The resonance parameters were adopted from the new Atlas of Neutron Resonances. In the fast region, all open reaction channels were evaluated with the reaction...

Description
Summary:Neutron-induced cross sections for 99 Tc were evaluated from 10 −5 eV to 20 MeV for the U.S. ENDF/B-VII.0 library released in December 2006. The resonance parameters were adopted from the new Atlas of Neutron Resonances. In the fast region, all open reaction channels were evaluated with the reaction code EMPIRE-2.19. Comparison of the present evaluation with microscopic measurements and data recommended by European (JEFF-3.1) and Japanese (JENDL-3.3) libraries is presented.
