Identifying structures in the continuum: Application to 16 Be
(American Physical Society, 2019)
Background: The population and decay of two-nucleon resonances offer exciting new opportunities to explore dripline phenomena. A proper understanding of these systems requires a solid description of the three-body (core+N ...

Transport coefficients for dense hard-disk systems
(American Physical Society, 2006)
A study of the transport coefficients of a system of elastic hard disks based on the use of Helfand-Einstein expressions is reported. The self-diffusion, the viscosity, and the heat conductivity are examined with averaging ...

Alpha-particle production in the 6He+120Sn collision
(Institute of Physics Publishing, 2020)
Alpha particle energy distributions in the 6He+120Sn collision have been measured at 7 bombarding energies above the Coulomb barrier. A phenomenological analysis of the centroids of the experimental distributions was ...

Scalar two-level boson model to study the interacting boson model phase diagram in the Casten triangle
(American Physical Society, 2006)
We introduce a simple two-level boson model with the same energy surface as the Q-consistent interacting boson model Hamiltonian. The model can be diagonalized for large number of bosons and the results used to check ...

El transporte de carga en sólidos moleculares amorfos: un estudio mediante simulación de Monte-Carlo
(1993)
La invención de las técnicas electrográficas, que han dado lugar a lo que se conoce comercialmente como xerografía, ha supuesto una verdadera revolución en el campo del procesado de documentos puesto que es dicha técnica ...

Combination of fast-ion diagnostics in velocity-space tomographies
(IOP Publishing, 2013-06)
Fast-ion Dα (FIDA) and collective Thomson scattering (CTS) diagnostics provide indirect measurements of fastion velocity distribution functions in magnetically confined plasmas. Here we present the first prescription ...

Reinforcement Learning and Physics
(MDPI, 2021)
Machine learning techniques provide a remarkable tool for advancing scientific research, and this area has significantly grown in the past few years. In particular, reinforcement learning, an approach that maximizes a ...

Coulomb breakup in a transformed harmonic oscillator basis
(American Physical Society, 2006-05-10)
The problem of Coulomb breakup in the scattering of a two-body loosely bound projectile by a heavy target is addressed. A basis of transformed harmonic oscillator (THO) wave functions is used to discretize the projectile ...

The 139 La(n ,γ) cross section: Key for the onset of the s -process
(The American Physical Society, 2007)
The nuclear resonance parameters and the capture cross section of the neutron magic isotope La139 have been measured relative to Au197 in the energy range of 0.6 eV to 9 keV at the neutron time-of-flight (n_TOF) facility ...

Brownian motion in a granular gas
(American Physical Society, 1999)
The dynamics of a heavy particle in a gas of much lighter particles is studied via the Boltzmann-Lorentz equation with inelastic collisions among all particles. A formal expansion in the ratio of gas to tagged particle ...
