The objective of this paper is to present the results of an evaluation of the gadolinium isotopes with the main focus on the isotopes 155Gd and 157Gd. The evaluations were carried out in the resolved resonance region using the Reich-Moore formalism. The originality on the 155Gd and 157Gd evaluations is the addition of new high-resolution capture cross section measurements performed at the neutron time-of-flight, n_TOF facility for enriched samples and the statistical analysis of the resonance parameters. The resonance analysis was performed with the multilevel R-matrix code SAMMY together with the generalized least-squares technique based on the Bayes’ theory.
