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 ...

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 field theory of spin dealignment in strongly rotating nuclei and the vacuum polarization induced by pairing vibrations
(Elsevier, 1987)
Processes where particles are dressed by pairing vibrations and where their average field is modified by the Fock contribution of the pairing force are found to give rise to dynamical dealignments of the single-particle ...

Role of thermal fluctuations in the damping of the giant dipole resonance of spherical and deformed nuclei: 90Zr and 164Er
(Elsevier, 1987)
We study the damping width of the giant dipole resonance (GDR) built on the ground state and on excited states of 90Zr, which is spherical at zero spin and temperature, and 164Er which is deformed. Neither of these nuclei ...

Valoración de la contaminación de neutrones producidos por un acelerador lineal de electrones (18 MV) de uso clínico
(1987)
Los haces de radiación de altas energías ( 10 MEV) están generalmente contaminados con neutrones resultantes de la reacción (y n) producida por la interacción de los fotones con los elementos constituyentes del acelerador ...
