“…A better accuracy in the measured data would ultimately contribute towards the improvement of the theoretical model frameworks and precise nuclear data in astrophysics, and in many other applications. A current surge in research work for consistent capture cross section and resonance integral data has been clearly noted [7][8][9][10][11][12][13][14]. In this regard, the present author(s) have also studied the σ 0 and I 0 of 159 Tb [1], 57 Co [7], 74 Se, 75 As, etc.…”

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.

“…4 most of which were measured by our group, namely: 169 Tm(p,n) 169 Yb [2], 169 Tm(d,2n) 169 Yb [3,4], nat Er(a,xn) 169 Yb [5], nat Yb(a,x) 169 Lu ? 169 Yb [6], and The 3 He induced reactions on Tm and Yb were not included in this comparison because the proton and deuteron induced reactions on these targets are more productive and because they require higher energies and expensive 3 He beams.…”

Tárkányi et al [3] performed a detailed study on the excitation function of the 169 Tm(d,2n) 169 Yb process comparing the production yields of the reactor-based method and other charged particle induced reactions; Hermanne et al [4] extended the energy range up to 40 MeV. Király et al investigated the nat Er(a,xn) 169 Yb [5] and nat Yb(a,x) 169 Lu ?…”

Activation cross sections of deuteron induced reactions on ytterbium for production of 177g,173,172,171,170,169,167 Lu, 177,175,169 Yb and 173,168,167,165 Tm were extended up to 50 MeV deuteron energy. The new data are in acceptable agreement with the earlier experimental data in the overlapping energy region. The experimental data are compared with the predictions of the ALICE-D, EMPIRE-D and TALYS 1.4 (TENDL-2013 on-line library results) codes.
