The measurement has been performed with an optimized setup of two C6D6 scintillation detectors, which allowed us to reduce scattered neutron backgrounds down to a negligible level. Resonance parameters and radiative kernels have been determined for 16 resonances by means of an R-matrix analysis in the neutron energy range from 3 keV to 320 keV. Good agreement with previous measurements was found at low neutron energies, whereas substantial discrepancies appear beyond 45 keV. With the present results, we obtain an s-process contribution of 77±8% to the solar abundance of Pb207. This corresponds to an r-process component of 23±8%, which is important for deriving the U/Th ages of metal poor halo stars. © 2006 The American Physical Society.http://hdl.handle.net/123456789/1753210.1103/PhysRevC.74.0558025ISI:0002424095000560556-281374engAMERICAN PHYSICAL SOCPhysical Review C - Nuclear PhysicsELEMENTSNEUTRON-CAPTURESOLARCHRONOMETERSNUCLEOSYNTHESISABUNDANCESGALACTIC CHEMICAL EVOLUTIONGIANT BRANCH STARSResonance capture cross section of Pb207journalArticle2006Δημοσίευση σε περιοδικόPublication in journalΠυρηνική φυσικήNuclear Physicsisi - Physics, Nuclear includes resources on the study of nuclear structure, decay, radioactivity, reactions, and scattering.
