Nuclear physics for the Re/Os clock
(2008-01)
Dating the age of the universe by the beta-decay of (187)Re (t(1/2) = 41.2 Gyr) requires the accurate assessment of the s-process reaction flow. The daughter nucleus (187)Os as well as its immediate s-only neighbor (186)Os ...
The measurement of the (206)Pb(n,gamma) cross section and stellar implications
(2008-01)
The neutron capture cross section of (206)Pb has been measured at the CERN n_TOF spectrometer using a setup of two C(6)D(6) detectors. In the energy interval from 1 eV to 600 keV the cross section is dominated by resonances, ...
Capture cross section measurements of (186,187,188)Os at n_TOF : the resolved resonance region
(EDP Sciences, 2008)
The neutron capture cross sections of (186,187,188)Os have been measured at the CERN neutron time-of-flight facility, n_TOF, in the neutron energy range from 1 eV up to 1 MeV. In this contribution, we report the results ...
