Comment on “Pairing interaction and Galilei invariance”
(American Physical Society, 1999)
A recent article by Dussel, Sofia, and Tonina studies the relation between Galilei invariance and dipole energy weighted sum rule (EWSR). The authors find that the pairing interaction, which is neither Galilei nor Lorentz ...

Dynamical behavior of a one-dimensional Ising model submitted to continuous heating and cooling processes
(American Institute of Physics Publising LLC, 1994)
The evolution of a one-dimensional Ising model with Glauber dynamics and an extrinsic energy barrier, submitted to continuous cooling and heating processes, is studied. The model is shown to exhibit many of the properties ...

Quasielastic scattering from relativistic bound nucleons: Transverse-longitudinal response
(American Physical Society, 1999-12-27)
Predictions for electron induced proton knockout from p1/2 and p3/2 shells in 16O are presented using various approximations for the relativistic nucleonic current. Results for differential cross section, transverse-longitudinal ...

Aplicación de la espectrometría de masas con aceleradores a la determinación de radionúclidos de semivida grande en la naturaleza
(1999-05-28)
La detección de radionúclidos de periodo de semidesintegración grande en muestras ambientales es interesante, entre otras razones, por la posibilidad que ofrece de trazar y comprender procesos naturales como mezclas de ...

Finite-size effects on multibody neutrino exchange
(American Physical Society, 1998-10-01)
We use an effective Lagrangian to study the multibody massless neutrino exchange inside a finite neutron star. Following Schwinger, we show how the total interaction energy density is computed by comparing the values of ...

The Location of Stellar Clusters in the Big Dent: an Age Gradient along the Z-Axis
(IOP Publishing Ltd., 1995-07-20)
The ages and locations of stellar clusters and individual Cepheid stars in the depression called the "Big Dent" are analyzed. The Z-locations of the cluster sample display a well-defined Z-age stratification. The Cepheid ...

Reply to ''Comment on 'Dynamical polarization potential due to the excitation of collective states' ''
(American Physical Society, 1993)
This is a reply to the preceding Comment. We confirm the results of our paper. The differences between our calculations and those of the preceding Comment come mainly from the form factors. Our random-phase-approximation-based ...
