Analysis and evaluation of thermal and resonance neutron activation data

A generalized least-squares technique has been applied to produce a consistent set of thermal and epithermal neutron activation data for the following 20 nuclides produced by neutron capture: ⁴⁶Sc, ⁵¹Ti, ⁵¹Cr, ⁵²V, ⁵⁶Mn, ⁵⁹Fe, ⁶⁰Co, ⁷⁵Se, ⁸⁶Rb, ⁹⁵Zr, ⁹⁷Zr, ¹²⁴Sb, ¹³¹Ba, ¹³⁴Cs, ¹⁴⁰La, ¹⁴¹Ce, ¹⁶⁰Tb, ¹⁸¹Hf, ¹⁸²Ta and ¹⁹⁸Au. The technique combines available information on nuclear data from the literature with measured activation data irradiated in nine reactor positions in Germany, the U.K. and Japan.Most of the solution nuclear data showed a distinct improvement, some by a large amount. These have been compared with the most recent evaluation.
