Neutron transmission and capture measurements and analysis of Dy from 0.01 to 550 eV

Highlights: • Transmission and capture measurements from thermal to 550 eV on Dy and ¹⁶⁴Dy samples. • Bayesian analysis provided resonance parameters from the combined measurements. • Liquid samples were used to obtain uniformly thin ¹⁶⁴Dy samples. • The ¹⁶⁴Dy thermal cross section and resonance integral were obtained from these measurements. • Improvements were made for the 5.45 eV ¹⁶²Dy resonance parameters. - Abstract: Neutron capture and transmission measurements were carried out from 0.01 to over 600 eV on both natural Dy and samples highly enriched in ¹⁶⁴Dy. These data were analyzed for resonance parameters utilizing the SAMMY Bayesian analysis code to simultaneously fit both the capture and transmission data. Parameters were obtained for 17 resonances in Dy isotopes up to 18 eV and for the ¹⁶⁴Dy resonances near 147, 450 and 540 eV. The thermal capture cross section (at 0.0253 eV) and capture resonance integral were determined for ¹⁶⁴Dy.
