The relatively good agreement between 3182300100032 Calamand data and our data is thus only incidental. 3182300100033 The neglect of low energy neutrons in our work 3182300100034 seems to be compensated by the higher neutron flux in 3182300100035 the 0.5-1.5 MeV energy region of the TRIGA reactor 3182300100036 than that of the pure 235U fission spectrum. 3182300100037 STATUS (TABLE) Table 2 of Radiochim.Acta 108(2020)511 3182300100038 (APRVD) Proof-read by Md.
