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 ...

Hierarchical star formation: Stars and stellar clusters in the Gould Belt
(Oxford University Press, 2009)
We perform a study of the spatial and kinematical distribution of young open clusters in the solar neighbourhood, discerning between bound clusters and transient stellar condensations within our sample. Then, we discriminate ...

Extracting three-body breakup observables from continuum-discretized coupled-channels calculations with core excitations
(American Physical Society, 2017)
Core-excitation effects in the scattering of two-body halo nuclei have been investigated in previous works. In particular, these effects have been found to affect in a significant way the breakup cross sections of neutron-halo ...

Sawtooth patterns in force-extension curves of biomolecules: An equilibrium-statistical-mechanics theory
(American Physical Society, 2013)
We analyze the force-extension curve for a general class of systems, which are described at the mesoscopic level by a free energy depending on the extension of its components. Similarly to what is done in real experiments, the ...

Experimental investigation of ground-state properties of 7H with transfer reactions
(Elsevier, 2022)
The properties of nuclei with extreme neutron–to–proton ratios, far from those naturally occurring on Earth, are key to understand nuclear forces and how nucleons hold together to form nuclei. 7H, with six neutrons and a ...

Colorimetric energy sensitive scintillator detectors based on luminescent multilayer designs
(Elsevier, 2018)
In this work we present a new concept for energy sensitive radiation-beam scintillator detectors based on a luminescent multilayer design, where each layer within the stack consists of a rare-earth-doped highly transparent ...

Neutron-proton pair transfer reactions and corresponding Weisskopf-type units
(Elsevier, 2022)
We introduce the concept of neutron-proton two-particle units (np-Weisskopf units) to be used in the analysis of the (3He,p) and (p,3He) reactions on nuclei along the N=Z line. These are presented for the conditions ...

Asymmetric relativistic Fermi gas model for quasielastic lepton-nucleus scattering
(American Physical Society, 2018)
We develop an asymmetric relativistic Fermi gas model for the study of the electroweak nuclear response in the quasielastic region. The model takes into account the differences between neutron and proton densities ...

Comment on "from Coulomb Excitation Cross Sections to Nonresonant Astrophysical Rates in Three-body Systems: The Ne 17 Case"
(American Physical Society, 2020)
Parfenova et al. state in [Phys. Rev. C 98, 034608 (2018)2469-998510.1103/PhysRevC.98.034608] that the results presented by Casal et al. [Phys. Rev. C 94, 054622 (2016)2469-998510.1103/PhysRevC.94.054622] concerning the ...

Realistic spectral function model for charged-current quasielastic-like neutrino and antineutrino scattering cross sections on C 12
(American Physical Society, 2019)
A detailed study of charged current quasielastic neutrino and antineutrino scattering cross sections on a C12 target with no pions in the final state is presented. The initial nucleus is described by means of a realistic ...
