%D 2011 %B Proceedings of JEFF/EFF Meeting May 2011 NEA %T Updated Co-58 evaluation for background capture reaction (MT102) (JEF/DOC-1367) %I Nuclear Energy Agency %A Adriana Ortiz %A Oscar Luis Cabellos de Francisco %C Paris, Francia %L upm11535 %X The neutron capture (n,gamma) cross-section for 27-Co-58 theoretically presents a single resonance for 9 eV. However, after plotting the processed library, a discontinuity is made clear as the cross section plummets down to cero in a small range of energy where the peak of the resonance would be expected.
