    • High-accuracy determination of the 238U/ 235U fission cross section ratio up to ˜ 1 GeV at n_TOF at CERN 

      Paradela, C.; Calviani, Marco; Tarrío, D.; Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Gómez Hornillos, María Belén; Pretel Sánchez, Carme; Riego Pérez, Albert (2015-02-09)
      Article
      Accés obert
      The U238 to U235 fission cross section ratio has been determined at n_TOF up to ˜1 GeV, with two different detection systems, in different geometrical configurations. A total of four datasets has been collected and compared. ...

    • Neutron-induced fission cross section of Pu-240 from 0.5 MeV to 3 MeV 

      Salvador Castiñeira, Paula Genoveva; Brys, Tomasz; Eykens, Roger; Hambsch, Franz Josef; Gook, A.; Moens, André; Oberstedt, Stephan; Sibbens, Geodele; Vanleeuw, David; Vidali, Marzio; Pretel Sánchez, Carme (2015-07-21)
      Article
      Accés obert
      Pu-240 has recently been pointed out by a sensitivity study of the Organization for Economic Cooperation and Development (OECD) Nuclear Energy Agency (NEA) to be one of the isotopes whose fission cross section lacks accuracy ...

    • Neutron-induced fission cross sections of Pu-242 from 0.3 MeV to 3 MeV 

      Salvador Castiñeira, Paula Genoveva; Brys, Tomasz; Eykens, Roger; Hambsch, Franz Josef; Gook, A.; Moens, André; Oberstedt, Stephan; Sibbens, Geodele; Vanleeuw, David; Vidali, Marzio; Pretel Sánchez, Carme (2015-10-13)
      Article
      Accés obert
      The majority of the next generation of nuclear power plants (GEN-IV) will work in the fast-neutron-energy region, as opposed to present day thermal reactors. This leads to new and more accurate nuclear-data needs for some ...
