The thermal-neutron cross-section and the resonance integral for the Yb-174(n,gamma)Yb-175 reaction were measured by the I activation method using a Mn-55 monitor as single comparator. Analytical grade MnO2 and Yb2O3 powder samples with and without a cylindrical 1 mm Cd shield box were irradiated in an isotropic neutron field obtained from three Am-241-Be neutron sources. The gamma-ray spectra from the activated samples were measured with a calibrated n-type high-purity Ge detector. The experimental results were corrected for the correction factors calculated for thermal and epithermal neutron self-shielding effects, epithermal neutron spectrum shape and gamma-ray self attenuation. Thus, the thermal neutron cross-section for the Yb-174(n,gamma) Yb-175 reaction is found to be 126.5 +/- 6.6 b, relative to that of the Mn-55 monitor. The resonance integral value for the Yb-174(n,gamma)Yb-175 reaction is found to be 59.6 +/- 8.5 b, at cadmium cut-off energy of a 0.55 eV. Using the measured cadmium ratios of Mn-55 and Yb-174, the result for resonance integral of the Yb-174(n, gamma)Yb-175 reaction has also been obtained relative to the reference value of the Mn-55 monitor. The present results for the Yb-174(n,gamma)Yb-175 reaction agree well only with the recent experimental ones obtained by Kafala et at.  and De Corte and Simonits  within uncertainty limits. However, the previously reported experimental data for the thermal neutron cross-section for this reaction are distributed between 24 and 141 b, and similarly the experimental values for the resonance integral value also show a large scatter in the range of 30-69 b.
