“…0.73±0.17 b. The Atlas value is based on two isomeric ratio measurements by Namboodiri et al [52] and Dzantiev et al [53] which are in excellent agreement, while the ENDF/B-VII.1 value is based on an older evaluation [49].…”

We present calculations of neutron thermal cross sections, Westcott factors, resonance integrals, Maxwellianaveraged cross sections and astrophysical reaction rates for 843 ENDF materials using data from the major evaluated nuclear libraries and European activation file. Extensive analysis of newly-evaluated neutron reaction cross sections, neutron covariances, and improvements in data processing techniques motivated us to calculate nuclear industry and neutron physics quantities, produce s-process Maxwellian-averaged cross sections and astrophysical reaction rates, systematically calculate uncertainties, and provide additional insights on currently available neutron-induced reaction data. Nuclear reaction calculations are discussed and new results are presented. Due to space limitations, the present paper contains only calculated Maxwellian-averaged cross sections and their uncertainties. The complete data sets for all results are published in the Brookhaven National Laboratory report.

“…This research is aimed to accumulate more experimental data since there are very rare data for these nuclei in the existing literature and for the theoretical interpretation many new measurements are needed. We found only two works [13,14] for 108 Pd and three ones [14][15][16] for 110 Pd nuclei. The obtained results can make the Nuclear Data Bank richer and provide data for the interpretation of the IRs by different theoretical models.…”

“…Table 4 presents the IRs in 108 Pd(n, γ) 109m,g Pd and 110 Pd(n, γ) 111 Pd capture reactions induced by thermal, resonant and mixed thermal-resonant neutrons obtained in our experiments and from other authors in Refs. [14][15][16]. For the interpretation, the IR values in 110 Pd(n, 2n) 109 Pd, 110 Pd(γ, n) 109 Pd and 114 Cd(n, α) 111 Pd reactions, taken from Refs.…”

“…In fact, the difference between our results and the data obtained in refs. [14][15][16] may come from the following sources: (a) In Refs. [14][15][16], the neutron source was a reactor, while in our experiment the neutron flux was obtained from the accelerator.…”

“…Their result was shown to be much higher than the calculated one by the Huizenga-Vandenbosch method [11,12]. Namboodiri et al [16] studied the IRs in (n, γ) reaction on 110 Pd with the radiochemical techniques and the results were compared with the Huizenga-Vandenbosch model calculations [11,12]. The authors show that the calculated IR significantly depends on the number of gamma rays in the cascade of de-excitation of the residual nucleus and the spin cut-off parameter.…”

The isomeric ratios in neutron capture reactions, induced by thermal, resonant and mixed thermal-resonant neutrons on 108 Pd and 110 Pd nuclei have been measured by the activation method. The data analysis and necessary corrections as the self-absorption and summing cascade effects were made in gamma rays radioactivity measurements to improve the precision of the isomeric ratio determination. The results were discussed and compared with those in the existing literature. The isomeric ratios in 108 Pd(n, γ) 109m,g Pd and 110 Pd(n, γ) 111m,g Pd reactions, induced by mixed thermal-resonant neutrons as well as in 110 Pd(n, γ) 111m,g Pd reaction, induced by resonant neutron are first measurements.
