“…The other literature value where the difference of the present σ 0 is more than 10% is of Steinnes [43]. The better agreements of the present measurement within less than 2% are with the values of DeCorte [31] and Zimmerman et al [44]. In other cases, the agreements are within 4%.…”

The important aspect revealed in this inter-comparison study was that when we set the alpha parameter to zero (i.e., to 1/E ideality condition), the I 0 value changed greatly (i.e., to 699 b with respect to cobalt and 637 b with respect to gold).…”

Thermal neutron cross section / Resonance integral / 165 Ho (n, γ ) 166 Ho reaction / Reaction rate / Flux distribution/ Flux deviation parameter Summary. The ground state thermal neutron cross section and the resonance integral for the 165 Ho(n, γ ) 166 Ho reaction in thermal and 1/E regions, respectively, of a thermal reactor neutron spectrum have been measured experimentally by activation technique. The reaction product, 166 Ho in the ground state, is gaining considerable importance as a therapeutic radionuclide and precisely measured data of the reaction are of significance from the fundamental point of view as well as for application. In this work, the spectrographically pure holmium oxide (Ho 2 O 3 ) powder samples were irradiated with and without cadmium covers at the IEA-R1 reactor (IPEN, São Paulo), Brazil. The deviation of the neutron spectrum shape from 1/E law was measured by co-irradiating Co, Zn, Zr and Au activation detectors with thermal and epithermal neutrons followed by regression and iterative procedures. The magnitudes of the discrepancies that can occur in measurements made with the ideal 1/E law considerations in the epithermal range were studied.The measured thermal neutron cross section at the Maxwellian averaged thermal energy of 0.0253 eV is 59.0 ± 2.1 b and for the resonance integral 657 ± 36 b. The results are measured with good precision and indicated a consistency trend to resolve the discrepant status of the literature data. The results are compared with the values in main libraries such as ENDF/B-VII, JEF-2.2 and JENDL-3.2, and with other measurements in the literature.

“…As seen in Table 6, the experimental and the evaluated values for the thermal neutron cross-section of the 165 Ho(n,c) 166g Ho reaction are varied from 58 [8] to 67 barn [23,27]. The present result of 59.7 ± 2.5 barn is in good agreement within 4.2% (1r) with the experimental data obtained by Rajput et al [3], Yucel et al [5], De Corte [6], Holden [8], Kafala et al [10], De Corte and Simonits [12], Gryntakis et al [13], Mughabghab [14], Simonits et al [15], Heft [16], Ryves and Zieba [20], Zimmerman et el., [26] and Seren et al, [31]. However, the present result differs from the evaluated results of ENDF/B-VII.0 [4], Mughabghab [7], JFF2.2 [11], and also some experimental data of Danon et al [9], Erdtmann [17], Steinnes [21], Walker [22], Scoville and Rogers [23], THAI-AEC-10 [25], Stephenson [27], Keisch and Faler [29], and Pomerance [30] by 5.5-12.2%.…”
