    The 235U(n,f) cross section was measured in a wide energy range at n_TOF relative to 6Li(n,t) and 10B(n,alpha), with high resolution and in a wide energy range, with a setup based on a stack of six samples and six silicon ...

  • Neutron capture on ^{205}Tl: depicting the abundance pattern of lead isotopes in s-process nucleosynthesis 

    Casanovas Hoste, Adrià; Tarifeño Saldivia, Ariel Esteban; Domingo-Pardo, C; Calviño Tavares, Francisco (2018-01-10)
    External research report
    Open Access
    We propose to use the TOF technique to measure the neutron capture cross section of 205Tl(n,gamma) over the full energy range of stellar interest. An accurate measurement of this cross section is needed for a complete and ...

  • Radiative capture on 242Pu for MOX fuel reactors 

    Guerrero, Carlos; Balibrea-Correa, J.; Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere (2013-09-25)
    External research report
    Open Access
    The use of MOX fuel (mixed-oxide fuel made of UO2 and PuO2) in nuclear reactors allows substituting a large fraction of the enriched Uranium by Plutonium reprocessed from spent fuel. Indeed around 66% of the plutonium from ...
