Measurement of the radiative neutron capture cross section of Pb-206 and its astrophysical implications
(2007-10)
The (n,gamma) cross section of Pb-206 has been measured at the CERN n_TOF facility with high resolution in the energy range from 1 eV to 620 keV by using two optimized C6D6 detectors. In the investigated energy interval ...
Neutron reactions and nuclear cosmo-chronology
(Elsevier, 2007-07)
The beta-decay of Re-187 (t(1/2) = 42.3 Gyr) represents a suited cosmo-chronometer for the age of the r-process abundances, since the radiogenic part of the daughter isotope (OS)-O-187 is defined by the difference between ...
Measurement of the neutron capture cross section of the s-only isotope Pb-204 from 1 eV to 440 keV
(2007-01)
The neutron capture cross section of Pb-204 has been measured at the CERN n_TOF installation with high resolution in the energy range from 1 eV to 440 keV. An R-matrix analysis of the resolved resonance region, between 1 ...
