Nuclear excitations as coupled one and two random-phase-approximation modes
(American Physical Society, 2016)
We present an extension of the random-phase approximation (RPA) where the RPA phonons are used as building blocks to construct the excited states. In our model, that we call double RPA (DRPA), we include up to two RPA ...

Near-earth object 2012XJ112 as a source of bright bolides of achondritic nature
(Blackwell Publishing Ltd, 2014)
We analyse the likely link between the recently discovered near-Earth object 2012XJ112 and a bright fireball observed over the south of Spain on 2012 December 27. The bolide, with an absolute magnitude of -9 ± 1, was ...

Three-body nuclei and their astrophysical implications: The case of 6He
(American Institute of Physics, 2013)
The analytic THO method [1] is generalized to study three-body nuclei of astrophysical interest, and applied to 6He. Results are consistent with previous publications and experimental data [2, 3].

Phase diagram of the two-fluid Lipkin model: A "butterfly" catastrophe
(American Physical Society, 2016-03-31)
Background: In the past few decades quantum phase transitions have been of great interest in nuclear physics. In this context, two-fluid algebraic models are ideal systems to study how the concept of quantum phase transition ...

Be 9 elastic scattering on Pb 208 and Al 27 within a four-body reaction framework
(American Physical Society, 2015)
We investigate low-energy Be9 elastic scattering on two different targets (heavy, light) within a four-body framework using the continuum-discretized coupled-channels (CDCC) method. The Be9 projectile is described in an ...

Density dependence of 2p-2h meson-exchange currents
(American Physical Society, 2017-06-12)
We analyze the density dependence of the contribution of meson-exchange currents to the lepton-nucleus inclusive cross section in the two-particle two-hole channel. The model is based on the relativistic Fermi gas, where ...

Evidence of strong dynamic core excitation in 19C resonant break-up
(American Physical Society, 2016)
The resonant breakup of 19C on protons measured at RIKEN [Y. Satou et al., Phys. Lett. B 660, 320 (2008)] is analyzed in terms of a valence-core model for 19C that includes possible core excitations. The analysis of ...

Quasi-stellar objects in the ALHAMBRA survey: I. Photometric redshift accuracy based on 23 optical-NIR filter photometry
(EDP Sciences, 2012)
Context. Even the spectroscopic capabilities of today's ground and space-based observatories can not keep up with the enormous flow of detections (>10 5 deg -2) unveiled in modern cosmological surveys as: i) would be ...

Relativistic description of final-state interactions in neutral-current neutrino and antineutrino cross sections
(American Physical Society, 2013)
We evaluate semi-inclusive neutral-current quasielastic differential neutrino and antineutrino cross sections within the framework of the relativistic impulse approximation. The results of the relativistic mean-field and ...

Spectroscopy and orbital analysis of bright bolides observed over the Iberian Peninsula from 2010 to 2012
(Oxford University Press, 2013)
We present the analysis of the atmospheric trajectory and orbital data of four bright bolides observed over Spain, one of which is a potential meteorite dropping event. Their absolute magnitude ranges from -10 to -11. Two ...
