Excitation of Toroidal Alfvén Eigenmodes with Counter-current NBI in the TCV Tokamak
(Institute of Physics Publishing, 2023)
In Tokamak á Configuration Variable (TCV), unstable modes excited by resonant interaction between the shear Alfvèn waves in continuum gaps and energetic particles have been observed in scenarios with neutral beam injection ...

Atomic transitions and the first ionization potential of promethium determined by laser spectroscopy
(American Physical Society, 2019)
The atomic spectrum of neutral promethium has been studied extensively by laser resonance ionization spectroscopy. We report on more than 1000 atomic transitions in the blue and near infrared spectral ranges, most of them ...

Analytical expressions for the dispersive contributions to the nucleon-nucleus optical potential
(American Physical Society, 2003-06-01)
Analytical solutions of dispersion relations in the nucleon-nucleus optical model have been found for both volume and surface potentials. For the energy dependence a standard Brown-Rho function has been assumed for both ...

Impact of Charge Collection Efficiency and Electronic Noise on the Performance of Solid-state 3D Microdetectors
(Institute of Physics Publishing, 2020)
Microdosimetry has been traditionally performed through gaseous proportional counters, although in recent years different solid-state microdosimeters have been proposed and constructed for this task. In this paper, we ...

Breakup of 6Li + p at near-barrier energies and the effect on elastic scattering
(American Physical Society, 2017)
Exclusive breakup measurements have been performed for the Li6+p system in inverse kinematics at Li6 incident energies of 25 and 29 MeV. The results are considered in the Continuum Discretized Coupled-Channels framework, ...

Elastic scattering for the system 6Li + p at near barrier energies with MAGNEX
(American Institute of Physics, 2015)
Elastic scattering measurements have been performed for the 6Li+p system in inverse kinematics at the energies of 16, 20, 25 and 29 MeV. The heavy ejectile was detected by the large acceptance MAGNEX spectrometer at the ...

Fusion of 8He with 206Pb around Coulomb barrier energies
(EDP Sciences, 2011)
The experimental study of the fusion of light neutron-rich nucleus 8He with 206Pb is reported in this work. A fusion stack of 206Pb targets has been used for this study. The most prominent evaporation residue (210Po), which ...

Buckling in a Rotationally Invariant Spin-elastic Model
(American Physical Society, 2023)
Scanning tunneling microscopy experiments have revealed a spontaneous rippled-to-buckled transition in heated graphene sheets, in absence of any mechanical load. Several models relying on a simplified picture of the ...

A Symmetry-Adapted Algebraic Approach to Molecular Spectroscopy
(Scielo, 1996)
We apply a symmetry-adapted algebraic model to the vibrational excitations in D_3h and T_d molecules. A systematic procedure is used to establish the relation between the algebraic and configuration space formulations. In ...

Optimal filter systems for photometric redshift estimation
(IOP Publishing Ltd., 2009)
In the coming years, several cosmological surveys will rely on imaging data to estimate the redshift of galaxies, using traditional filter systems with 4-5 optical broad bands; narrower filters improve the spectral resolution, ...
