Quadrupole moments and E2 transitions in the O(6) limit of the IBM
(Elsevier, 1988)
Quadrupole moments and E2 transitions in the O(6) limit of the interacting boson model are studied within a formalism based on the intrinsic frame. We show that the values of these quantities for both ground- and β-bands ...

Double folding with a density-dependent effective interaction and its analytical approximation
(American Physical Society, 1981)
The real part of the optical potential for heavy ion elastic scattering is obtained by double folding of the nuclear densities with a density-dependent nucleon-nucleon effective interaction which was successful in describing ...

Polarization effects due to coupling of elastic to compound states
(Elsevier, 1987)
From a compound nucleus level-density-dependent imaginary potential an energy-and angular-momentum-dependent polarization potential is obtained by using the dispersion relation. The effect of coupling in this way the ...

Nonequilibrium phase transition to a time-dependent probability density for a model of charge-density waves
(American Institute of Physics Publising LLC, 1987)
A nonequilibrium phase transition to a stable time-periodic one-particle probability density is found in a modified Fukuyama-Lee model of charge-density waves. The classical single-phase model of Grüner, Zawadowski, and ...

Analysis of nonlinear transport in Couette flow
(American Physical Society, 1989)
The nonlinear Bhatnagar, Gross, and Krook [Phys. Rev. 94, 511 (1954)] kinetic equation is solved for boundary conditions leading to planar Couette flow and heat transport. In the limit of zero Knudsen number but arbitrary ...

Dispersive contribution to the nucleus-nucleus potential
(American Physical Society, 1987)
With a simple parametrization of the empirical imaginary potential depths, the real potential induced by a dispersion relation is calculated analytically for the elastic scattering of O16 by several target nuclei. Between ...

Effect of elastic transfer in sub-barrier fusion between similar nuclei
(American Physical Society, 1987)
We study the effect of the elastic transfer process on sub-barrier fusion reactions between similar nuclei. The coupling to the elastic transfer channel is described in terms of a parity dependent potential, directly ...

Aplicación y desarrollo de modelos compartimentales para el estudio de la dispersión de radionuclidos en el medio ambiente y en el cuerpo humano
(1987)
Se ha aplicado la técnica de modelos compartiméntales al estudio de la dispersión de radionúclidos en el ambiente marino y en el cuerpo humano. En cuanto a la primera aplicación hemos construido un modelo que nos ha ...

Nuclear-structure dependence of the fusion cross section for heavy ions
(Elsevier, 1980)
The energy dependence of the fusion cross section and its maximum value are well predicted, for a wide range of nuclei and energies, by introducing information on the nuclear matter density distribution into a simple formula
