Slow logarithmic relaxation in models with hierarchically constrained dynamics
(American Physical Society, 2001)
A general kind of model with hierarchically constrained dynamics is shown to exhibit logarithmic anomalous relaxation similar to a variety of complex strongly interacting materials. The logarithmic behavior describes most ...

Population of mixed-symmetry states via α transfer reactions
(The American Physical Society, 2008)
Within the neutron-proton interacting boson model we study the population of mixed-symmetry states via α transfer processes. Closed expressions are deduced in the case of the limiting Uπ+ν(5) and SUπ+ν(3). We find that the ...

Electromagnetic transitions and structure in the Z = N nucleus 46 V
(American Physical Society, 2001-10-01)
The nucleus 46V has been studied in the reaction 24Mg(28Si,apn) 46V at 115 MeV beam energy, using both Au and Pb backed targets. Lifetimes were obtained for 14 levels with DSAM analysis. Experimental B (E2) reduced transition ...

Search for E(5) symmetry in nuclei: The Ru isotopes
(American Physical Society, 2002-01-01)
We carry out an interacting boson model study of the Ru isotopes using a U(5)-SO(6) transitional Hamiltonian with fixed parameters, where the variation is due only to the change in boson number N. Transitional behavior ...

Elastic scattering and total reaction cross sections for the 8Li + 12C system
(The American Physical Society, 2009)
The elastic-scattering angular distribution for 8Li on 12C has been measured at ELAB=23.9 MeV with 8Li radioactive nuclear beam produced by the Radioactive Ion Beams in Brazil facility. This angular distribution was analyzed ...

Estudio de la deposición asistida por plasma de láminas delgadas de óxido de silicio y siliconas
(2005-10-19)
La deposición asistida por plasma (PECVD) de láminas delgadas de óxido de silicio y siliconas es un proceso de gran interés debido a su posible aplicación en microelectrónica como materiales de baja constante dieléctrica ...

Few-body multiple scattering calculations for 6 He on protons
(American Physical Society, 2007)
The elastic scattering of the halo nucleus 6 He from a proton target at 717 MeV/nucleon is investigated within three different multiple-scattering formulations of the total transition amplitude. The factorized impulse a ...

Hints on the quadrupole deformation of the (1232)
(American Physical Society, 2006-04-24)
The E2/M1 ratio (EMR) of the (1232) is extracted from the world data in pion photoproduction by means of an effective Lagrangian approach (ELA). This quantity has been derived within a crossing symmetric, gauge invariant, ...
