Abstract
A series of (n,γ) neutron capture measurements on the lead isotopes and bismuth have been carried out at the CERN n_TOF installation in the neutron energy range from l eV up to 1MeV. With this set of measurements the energy differential (n, gamma) cross sections of 204,206,207Pb and 209Bi have been determined with good accuracy. The information obtained in this work becomes of interest for constraining r-process calenlations and in particular for thc Th/U cosmochronometer.File in questo prodotto:
