  • Experimental determination of the activity of a 252Cf source 

    Caballero Folch, Roger (Universitat Politècnica de CatalunyaUniversitat de Barcelona, 2011-06)
    Master thesis
    Open Access
    An important research line in nuclear physics nowadays is the study of unstable nuclei. Within this, one area of interest is the study of delayed neutron emission which is of relevance for di erent elds such as ...

    Caballero Folch, Roger (Universitat Politècnica de Catalunya, 2015-06-05)
    Doctoral thesis

    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 ...
  • 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)
    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 ...
  • 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)
    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 ...
