      Tesi
      Accés obert
      This thesis has aimed to improve the hydrogeological knowledge of the Port del Comte Massif (PCM), a karstic aquifer system located in the south-eastern sector of the Pyrenees that plays a strategic role in the provision ...

    • Dreams and needs: The application of isotopes to industry in Spain in the 1960s 

      Barca Salom, Francesc Xavier (2009-07)
      Article
      Accés obert
      ABSTRACT: The efforts to change the bleak image of the atom bomb galvanised the discourse on the peaceful applications of nuclear energy. This contributed to a utopian vision of nuclear energy, especially of the uses of ...

    • Energetics and Control of Ultracold Isotope-Exchange Reactions between Heteronuclear Dimers in External Fields 

      Tomza, Michal (APS, 2015-08-07)
      Article
      Accés obert
      We show that isotope-exchange reactions between ground-state alkali-metal, alkaline-earth-metal, and lanthanide heteronuclear dimers consisting of two isotopes of the same atom are exothermic with an energy change in the ...

    • Groundwater hydrodynamics of an Eastern Africa coastal aquifer, including La Niña 2016–17 drought 

      Ferrer Ramos, Nuria; Folch Sancho, Albert; Lane, Mike; Olago, Dan; Odida, Julius; Custodio Gimena, Emilio (Elsevier, 2019-04-15)
      Article
      Accés obert
      In 2016–17 much of East Africa was affected by a severe drought which has been attributed to Indian Ocean Dipole and El Niño Southern Oscillation conditions. Extreme events such as this have immediate and knock-on effects ...

    • Measurement of 139-La(n,gamma) Cross Section at n_TOF 

      Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Poch Parés, Agustí; Pretel Sánchez, Carme (American Institute of Physics (AIP), 2005)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The capture cross section of the 139La has been measured relative to 197Au standard at n_TOF. We provide here a short description of the experimental apparatus and of the data analysis procedures. The extracted resonance ...

    • Neutron-induced Fission Cross Section of240,242Pu 

      Salvador Castiñeira, P.; Brys, Tomasz; Eykens, Roger; Hambsch, Franz Josef; Gook, A.; Oberstedt, Stephan; Pretel Sánchez, Carme; Sibbens, Geodele; Vanleeuw, David; Vidali, Marzio (2015)
      Text en actes de congrés
      Accés obert
      A sensitivity analysis for the new generation of fast reactors [Salvatores (2008)] has shown the importance of improved cross section data for several actinides. Among them, the240,242Pu(n,f) cross sections require ...

    • 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
      Accés restringit per política de l'editorial
      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 ...

    • Radiative neutron capture cross-section measurement of ge isotopes at n_TOF CERN facility and its importance for stellar nucleosynthesis 

      Gawlik Ramiega, Aleksandra; Lederer-Woods, C.; Andrzejewski, Józef; Battino, U.; Mingrone, Federica; Weiss, Christina; Aberle, O.; Audouin, Ludmila; Bacak, Michael; Balibrea-Correa, J.; Barbagallo, Massimo; Barros, S.; Bécares, Vicente; Becvar, F.; Calviño Tavares, Francisco; Casanovas Hoste, Adrià; Cortés Rossell, Guillem Pere (2021-04-01)
      Article
      Accés obert
      This manuscript summarizes the results of radiative neutron capture cross-section measurements on two stable germanium isotopes, 70Ge and 73Ge. Experiments were performed at the n_TOF facility at CERN via the time-of-flight ...

    • ß -delayed neutron emissions from N>50 gallium isotopes 

      Yokoyama, Rin; Grzywacz, Robert; Rasco, B. Charles; Brewer, Nathan; Rykaczewski, Krzysztof P.; Dillmann, Iris; Taín Enríquez, José Luis; Nishimura, Shunji; Ahn, D.S.; Algora, Alejandro; Allmond, James Mitchell; Agramunt Ros, Jorge; Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Tarifeño Saldivia, Ariel Esteban (American Physical Society, 2023-12-08)
