dc.description.abstract | The neutron capture cross section of 154Gd was measured from 1 eV to 300 keV in the experimental area
located 185 m from the CERN n_TOF neutron spallation source, using a metallic sample of gadolinium,
enriched to 67% in 154Gd. The capture measurement, performed with four C6D6 scintillation detectors,
has been complemented by a transmission measurement performed at the GELINA time-of-flight facility
(JRC-Geel), thus minimising the uncertainty related to sample composition. An accurate Maxwellian
averaged capture cross section (MACS) was deduced over the temperature range of interest for s process
nucleosynthesis modelling. We report a value of 880(50) mb for the MACS at kT = 30 keV, significantly
lower compared to values available in literature. The new adopted 154Gd(n,γ ) cross section reduces the
discrepancy between observed and calculated solar s-only isotopic abundances predicted by s-process
nucleosynthesis models. | es |
