    A prototype version of the BEta deLayEd Neutron detector, which is being developed for the FAIR/DESPEC experiment, has been used for the first time in an experiment at JYFL (Finland). This detector is based on 3He counters ...
  • Measurement of very low (alpha,n) cross sections of astrophysical interest 

    Taín, J.L.; Jordan Herrero, Donato; Agramunt Ros, Jorge; Algora, A.; Bandac, I; Bettini, S; Caballero Folch, Roger; Calviño Tavares, Francisco; Cano-Ott, D; Cortés Rossell, Guillem Pere; Domingo-Pardo, C; Fraile, L. M.; Garcia, A.R.; Gomez-Cadenas, J.J.; José Pont, Jordi; Longland, Richard; Mendoza, E (Institute of Physics (IOP), 2016)
    Article
    Open Access
    The reactions 13C( ; n)16O and 22Ne( ; n)25Mg are the primary sources of neutrons for the astrophysical s-process. The feasibility of cross section measurements within the respective Gamow windows is discussed in quantitative ...
  • New Beta-delayed neutron measurements in the light-mass fission group 

    Äystö, J.; Caballero Folch, Roger; Calviño Tavares, Francisco; Eronen, T.; Gelletly, W.; Gómez Hornillos, María Belén; Moore, I.; Penttila, H.; Reponen, M.; Riego Pérez, Albert; Rissanen, J.; Rubio, B.; Valencia, E. (2014-06-01)
    Article
    Restricted access - publisher's policy
    A new accurate determination of beta-delayed neutron emission probabilities from nuclei in the low mass region of the light fission group has been performed. The measurements were carried out using the BELEN 4 pi neutron ...
  • Total absorption spectroscopy study of Rb-92 decay: a major contributor to reactor antineutrino spectrum shape 

    Zakari-Issoufou, A.-A.; Fallot, M.; Porta, A.; Caballero Folch, Roger; Gómez Hornillos, María Belén; Gorlychev, V. (2015-09-04)
    Article
    Open Access
    The antineutrino spectra measured in recent experiments at reactors are inconsistent with calculations based on the conversion of integral beta spectra recorded at the ILL reactor. Rb-92 makes the dominant contribution to ...
  • ß-decay and ß-delayed neutron emission measurements at GSI-FRS Beyond N=126, for r-process nucleosynthesis 

    Caballero Folch, Roger; Benlliure, J.; Cortés Rossell, Guillem Pere; Bowry, M.; Calviño Tavares, Francisco; Dillmann, I.; Estradé, A.; Farinon, F.; Geissel, H.; Gelletly, W.; Gómez Hornillos, María Belén; Heil, M.; Nociforo, C.; Kurcewicz, J.; Marganiec, J.; Paradela, C.; Pietri, S.; Prochazka, A.; Maurice, S.; Riego Pérez, Albert; Rubio, B.; Weick, H.; Smith, K.M; Woody, R.W. (2014-06-01)
    Article
    Restricted access - publisher's policy
    New measurements of very exotic nuclei in the neutron-rich region beyond N=126 have been performed at the GSI facility with the fragment separator (FRS). The aim of the experiment is to determine half-lives and beta-delayed ...
  • ß-delayed neutron emission measurements around the third r-process abundance peak 

    Caballero Folch, Roger; Domingo Pardo, César; Cortés Rossell, Guillem Pere; Calviño Tavares, Francisco; Riego Pérez, Albert (2012)
    Conference lecture
    Restricted access - publisher's policy
    The elements heavier than iron are produced in the Universe mainly by means of the slow (s) and rapid (r) neutron capture processes (for a recent review see e.g. [1]). The latter nucleosynthesis mechanism occurs between ...
