      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 ...

    • Resonance neutron-capture cross sections of stable magnesium isotopes and their astrophysical implications 

      Massimi, Cristian; Koehler, Paul E.; Colonna, Nicola; Gunsing, Frank; Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Poch Parés, Agustí; Pretel Sánchez, Carme (2012-04-20)

      The neutron time-of-flight facility n_TOF at CERN, fully operational since 2002, combines a high instantaneous neutron flux with high energy resolution. The wide energy range and the high neutron flux per time-of-flight ...

    • 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)

      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 nucleosynthesis of heavy elements in Stars: The key isotope 25Mg 

      Massimi, Cristian; Koehler, Paul E.; Kopecky, Stefan; Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere (2013)
      Conference report
      Open Access
      We have measured the radiative neutron-capture cross section and the total neutron-induced cross section of one of the most important isotopes for the s process, the 25Mg. The measurements have been carried out at the ...
