Analysis of the elastic scattering measured with a 23.7 MeV 7Be beam on a 9Be target.
(American Institute of Physics, 2009)
We present new data for the reaction 7Be+9Be measured at Elab =23.7 MeV. The elastic scattering angular distribution has been analyzed using the phenomenological optical model and the coupled-channels method. In the ...

Heat flux in a vibrated granular gas: the diffusive heat conductivity coefficient
(AIP Publishing, 2005)
The transport coefficient coupling heat flux and density gradient in a granular gas is measured by taking advantage of the existence of a minimum in the temperature profile of an open vibrated granular medium. This temperature ...

Astrophysical S-factors for the p+16O and n+16O captures from the analysis of 16O(d,n)17F and 16O(d,p)17O transfer reactions
(American Institute of Physics, 2007)
Coupled reaction channels calculations were performed for the 16O(d,n)17F and 16O(d,p)17O transfer reactions for the ground and first excited states at several energies from Elab=2.29 MeV up to 3.27 MeV. A strong polarization ...

The Research Program at RIBRAS (Radioactive Ion Beams in Brasil)-III
(American Institute of Physics, 2010)
A part of the research program developed in the RIBRAS facility over the last four years is presented. Experiments using radioactive secondary beams of light exotic nuclei such as 6He, 7Be, 8Li on several targets have ...

The Nuclear Astrophysics program at n_TOF (CERN
(EDP Sciences: EPJ Open Access, 2017)
An important experimental program on Nuclear Astrophysics is being carried out at the n_TOF since several years, in order to address the still open issues in stellar and primordial nucleosynthesis. Several neutron capture ...

Quantum phase transitions in odd-A nuclei: The effect of the odd particle from spherical to oblate shapes
(Institute of Physics Publishing, 2015)
Quantum shape-phase transitions in odd-nuclei are investigated within the framework of the interacting boson-fermion model (IBFM). We consider the case of a single-j fermion coupled to an even-even boson core that performs ...

Probing 6He structure from proton inelastic collisions
(American Institute of Physics, 2006)
We explore the Hyperspherical Harmonics pseudostate method to describe the 6He continuum. The method is use it within the multiple scattering of the transition amplitude (MST) approach to study inelastic scattering of p-6He ...

Measurement of capture cross sections of 90,91,92,94,96Zr isotopes at n_TOF
(AIP Publishing, 2005)
The neutron capture cross sections for Zr isotopes have important implications in nuclear technologies as well in the field of nuclear astrophysics. The innovative features of the n_TOF CERN facility allowed for an accurate ...

Experimental investigation of exotic clustering in 13B and 14C using the resonance scattering method
(Institute of Physics Publishing, 2018)
In order to investigate the existence of molecular and/or exotic cluster configurations in Boron and Carbon n-rich isotopes we undertook two experiments: the first experimental study of exotic 9Li+α cluster states in 13B ...
