The work stems from a joint study between the Laboratory ASTRO (Department of Civil and Industrial Engineering - University of
Pisa), the municipality of Pisa and the province of Arezzo on the advan...
Cross sections for proton-induced reactions on Pd isotopes at energies relevant for the gamma process
Cross sections proton-induced reactions Pd isotopes energies relevant
2011/7/21
Proton-activation reactions on natural and enriched palladium samples were investigated via the activation technique in the energy range of E_p=2.75 MeV to 9 MeV, close to the upper end of the respect...
Opportunities to constrain astrophysical reaction rates for the s-process through determination of the ground state cross sections
astrophysical reaction rates s-process ground state sections
2011/7/21
Modern models of s-process nucleosynthesis in stars require stellar reaction rates with high precision. Most of the neutron capture cross sections in the s-process have been measured and for an increa...
