New experimental measurement of natEr(n ,γ ) cross sections between 1 and 100 eV
Abstract
162Er and 164Er are two of the 35 p nuclei, and their (n ,γ ) cross sections are important input parameters in nuclear astrophysics network calculations. The neutron capture cross section in the resonance region of isotopes and even the natural erbium (natEr) sample has not been measured experimentally according to the EXFOR database. The (n ,γ ) cross section of natEr, using C6D6 liquid scintillator and pulse height weighting techniques to measure prompt γ rays, has been measured in the energy range of 1-100 eV using a back streaming white neutron facility at China Spallation Neutron Source. The deduced neutron capture cross sections matches the evaluation databases ENDF/B-VIII.0, ENDF/B-VII.1, JENDL-4.0, and ROSFOND-2010, and resonance parameters extracted from the R -matrix code in the 1-100 eV region.
