Abstract
The nonideality of the epithermal neutron flux distribution at a reactor site can be described by a 1/E1+α spectrum representation, with parameter α being a measure of the nonideality. α-values were determined in 3 typical irradiation positions of the TRIGA MARK II reactor of the “Jozef Stefan” Institute, Ljubljana, Yugoslavia, using the “Cd-ratio for multi-monitor” method. The simpler “Cd-ratio for dual monitor” method (monitors:197Au−94Zr) also yielded reliable results. This characterisation is of use in the k0-method of NAA, which is recently introduced at the Institute.
