Neutron cross sections of $sup 59$Co below 100 keV

Technical Report ·
OSTI ID:4012121
The neutron cross sections for $sup 59$Co have been evaluated in the energy range 10$sup -5$eV-100 keV for ENDF/BIV. Total and scattering cross sections are described by multilevel Breit-Wigner resonance parameters and the capture cross section is calculated using a single level Breit-Wigner formalism. The evaluation differs from the previous ENDF/B-III (in the resonance region basically in two ways: (1) the resonance region has been extended from 35 keV to 100 keV, (2) to describe thermal capture, scattering, total cross sections, and polarization data, a single s-wave bound level with spin 3 is evoked rather than the previous two bound levels with spins 3 and 4. This follows from using a radiative width of 0.48 eV for the spin 4 resonance at 132 eV rather than the 0.40 of ENDF/BIII. Comparisons with existing measurements are made. 57 references, 9 tables, 10 figures (SDF)
