Abstract: | Direct measurements of the 10B(n, He) reaction rate have been made in ZPPR. The measurements were made by isotope-dilution mass spectrometric analysis of stainless-steel encapsulated samples of enriched 10B. The results demonstrate that direct measurements of the 10B reaction rate in ZPPR are obtainable to an accuracy of ~1%. Comparisons with calculations give a predicted-to-experiment value of ~0.93. This value is consistent with earlier Rockwell measurements in benchmark neutron fields and further supports a need for revision in the ENDF/B cross section for 10B above ~0.1 MeV. |
