Abstract: | A neutron spectrum-independent compound nuclear constant, Iko, is proposed for fission interference corrections in reactor NAA by parametric method. Ik0 values for eight major fission interference cases, belonging to three different types, have been determined in six irradiation positions (with
th/
e 13,7–134) of three research reactors in our Institute. The general agreement among experimental Ik0 's from different irradiation positions and between experimental and calculated Ik0 values for the same interference case verifies the validity of the method. Calculated Ik0 values for all the possible fission interferences are tabulated. Interferences from238U(n,) and232Th(n,) reactions and reactor fast neutron induced238U(n, f) and232Th(n, f) reactions are discussed. |
