Abstract

Measurements of the neutron activation constants Q 0 and k 0 for the 27Al(n, γ)28Al reaction have been performed in two irradiation channels with different spectral characteristics at the JSI TRIGA Mark II reactor. In the determination of Q 0 the fission spectrum contribution to the reaction rates has been corrected for. The final experimental value of the Q 0 factor was found to differ significantly from the adopted value in the k 0-database. The experimental value of the k 0 factor is in agreement with the recommended value in the k 0-database. The thermal cross-section and resonance integral for the reaction were found to be in good agreement with the values calculated from the cross-sections from the ENDF/B-VII.1 library.
