An R-matrix analysis of the resolved resonance region, between 1 eV and 100 keV, was carried out using the SAMMY code. In the interval between 100 keV and 440 keV we report the average capture cross section. The background in the entire neutron energy range was reliably determined from the measurement of a Pb208 sample. Other systematic effects in this measurement were investigated and precisely corrected by means of detailed Monte Carlo simulations. We obtain a Maxwellian average capture cross section for Pb204 at kT=30 keV of 79(3) mb, in agreement with previous experiments. However our cross section at kT=5 keV is about 35% larger than the values reported so far. The implications of the new cross section for the s-process abundance contributions in the Pb/Bi region are discussed. © 2007 The American Physical Society.http://hdl.handle.net/123456789/181461ISI:0002438960000610556-281310.1103/PhysRevC.75.01580675engAMERICAN PHYSICAL SOCPhysical Review C - Nuclear PhysicsCERNABUNDANCESMonte Carlo SimulationR-PROCESSMatrix AnalysisHigh ResolutionELEMENTSSOLARCHRONOMETERSNUCLEOSYNTHESISCross SectionGALACTIC CHEMICAL EVOLUTIONGIANT BRANCH STARSLEADMeasurement of the neutron capture cross section of the s-only isotope Pb204 from 1 eV to 440 keVjournalArticle2007Δημοσίευση σε περιοδικόPublication in journalΠυρηνική φυσικήNuclear Physicsisi - Physics, Nuclear includes resources on the study of nuclear structure, decay, radioactivity, reactions, and scattering.
