      Neutron capture cross sections in the keV neutron energy region are the key nuclear physics input to study the astrophysical slow neutron capture process. In the past years, a series of neutron capture cross section ...
    • Neutron induced reactions for the s process, and the case of Fe and Ni isotopes 

      Lederer, Claudia; Altstadt, Sebastian; Calviño Tavares, Francisco; Andriamonje, S.; Cortés Rossell, Guillem Pere (PoS - Proceedings of Science, 2012)
      Conference report
      Open Access
      Neutron capture cross sections are the key nuclear physics input to understand nucleosynthesis of the slow neutron capture process (s process). At the neutron time of flight facility n_TOF at CERN neutron capture cross ...
    • New measurement of the astrophysically important reaction 62Ni(n,gamma) at n-TOF 

      Lederer, Claudia; Andriamonje, S.; Andrzejewski, Józef; Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Gómez Hornillos, María Belén (PoS - Proceedings of Science, 2010)
      Conference report
      Open Access
      The neutron capture cross section of the reaction 62Ni(n,gamma) 63Ni was measured over a wide energy range from 1 eV to 1 MeV at the neutron time-of-flight facility n_TOF installed at CERN. Preliminary results show that ...

      The cross section of the Ni-62(n,gamma) reaction was measured with the time-of-flight technique at the neutron time-of-flight facility n_TOF at CERN. Capture kernels of 42 resonances were analyzed up to 200 keV neutron ...
    • 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
      Restricted access - publisher's policy
      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 ...
    • The role of Fe and Ni for S-process nucleosynthesis and innovative nuclear technologies 

      Taín, J.L.; Lederer, Claudia; Brugger, Matthias; Calviani, Marco; Andriamonje, S.; Ferrari, Alessio; Calviño Tavares, Francisco; Gómez Hornillos, María Belén; Cortés Rossell, Guillem Pere (2011-08-12)
