Importance of Giant-Resonance Excitation for the Surface Properties of the Heavy-Ion Optical Potential
(IOP Publishing Ltd., 1989-05-15)
An imaginary potential associated with the inelastic excitation of the nuclei is computed in a multiphonon excitation model based on the random phase approximation. The surface properties of this potential are found to be ...

Nuclear structure information obtained from charge radii
(Elsevier, 1985)
We analyze the nuclear structure information obtained from measurements of charge radii in even-even and even-odd nuclei terms of the interacting boson model. The observed deviations from the smooth behavior, R = R0A1 3, ...

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 ...

Prealignment B(E2)-anomaly in 124Xe
(Elsevier, 1983)
Lifetimes of 17 levels of 124Xe were measured using the Recoil Distance Doppler Shift method. An anomalous E2-reduction was observed, starting at Iπ = 8+ and Iπ = 5+ in the groundstate and in the quasi-gamma band respectively. ...

Random-phase-approximation-based dynamical polarization potential
(American Physical Society, 1989)
A dynamical polarization potential is defined taking into account the effects on the elastic channel due to the excitation of vibrational collective modes, described within the random-phase approximation. The probability ...

On the critical behavior of the Percus-Yevick equation for nontruncated potentials
(AIP Publishing, 1984-12)
We present a qualitative analysis on the influence of truncating a long‐ranged potential on the critical behavior of a fluid described by the Percus–Yevick equation. It is shown that a nonclassical equation of state for ...

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 ...

Efecto de las fluctuaciones sobre las ecuaciones de transporte en sistemas no lineales
(1982)
Se ha realizado un estudio crítico de las principales teorías estocásticas para el estudio de fenómenos de transporte en sistemas no lineales. A continuación se aborda el problema de fundamentar mediante un estudio mecánico ...
