    • Neutron spectroscopy of 26Mg states: constraining the stellar neutron source 22Ne(alpha, n) 25Mg 

      Massimi, Cristian; Altstadt, Sebastian; Andrzejewski, Józef; Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere (Elsevier, 2017-02-16)
      Article
      Accés obert
      This work reports on accurate, high-resolution measurements of the 25Mg(n, gamma )26Mg and 25Mg(n, tot) cross sections in the neutron energy range from thermal to about 300 keV, leading to a significantly improved 25Mg(n, ...
    • Neutron-induced fission cross sections of Th 232 and U 233 up to 1 GeV using parallel plate avalanche counters at the CERN n_TOF facility 

      Tarrío, Diego; Tassan Got, Laurence; Durán, I.; Leong, L.S.; Paradela Dobarro, Carlos; Audouin, Ludmila; Leal-Cidoncha, E.; Le Naour, Claire; Caamaño Fresco, Manuel; Ventura, Alberto; Altstadt, Sebastian; Andrzejewski, Józef; Barbagallo, Massimo; Bécares, Vicente; Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Gómez Hornillos, María Belén; Riego Pérez, Albert (American Physical Society, 2023-04-01)
      Article
      Accés obert
      The neutron-induced fission cross sections of 232 Th and 233 U were measured relative to 235 U in a wide neutron energy range up to 1 GeV (and from fission threshold in the case of 232 Th , and from 0.7 eV in case of 233 ...
    • New measurement of the 25Mg(n,gamma) reaction cross section 

      Massimi, Cristian; Koehler, Paul E.; Mingrone, Federica; Altstadt, Sebastian; Andrzejewski, Józef; Audouin, Ludmila; Barbagallo, Massimo; Bécares, Vicente; Becvar, F.; Belloni, Fabio; Berthoumieux, Eric; Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Riego Pérez, Albert (2014-05-01)
      Article
      Accés restringit per política de l'editorial
      The 25Mg(n,gamma) reaction cross-section has been measured at the neutron time-of-flight facility n TOF at CERN in 2003 and, with an improved experimental set up, in 2012. These measurements aim at addressing important ...

      Accés restringit per política de l'editorial
      We have used the 4p BaF2 gamma-ray detector array at the n TOF neutron time-of-flight facility at CERN for an experiment in order to determine the spins of resonances of n+87Sr by measuring the gamma-ray spectra and ...
    • The (n,alpha) reaction in the s-process branching point 59Ni 

      Weiß, C.; Griesmayer, E.; Andrzejewski, Józef; Badurek, G.; Dressler, Rugard; Koehler, Paul E.; Lederer, Claudia; Altstadt, Sebastian; Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Gómez Hornillos, María Belén; Riego Pérez, Albert (2014-06-01)
      Article
      Accés restringit per política de l'editorial
      The (n,alpha) reaction in the radioactive 59Ni is of relevance in nuclear astrophysics as 59Ni can be considered as the first branching point in the astrophysical s-process. Its relevance in nuclear technology is especially ...
