The ratio of p and n yields in NC v(v̄) nucleus scattering and strange form factors of the nucleon
(Elsevier, 1998)
We calculate the ratio of proton and neutron yields in NC induced v(v̄)-nuc\eus inelastic scattering at neutrino energies of about 1 GeV. We show that this ratio depends very weakly on the nuclear models employed and that ...

Scattering of low-energy electrons by polar molecules: An analytic approach
(American Physical Society, 1998)
The scattering of low-energy electrons by polar molecules is considered. The excitation to the rotational states in the sudden approximation and the effect of the Coulomb dipole force to all orders are taken into account. ...

Relativistic current densities for bound spin-orbit partners and the longitudinal-transverse response in (e,ép) processes
(Elsevier, 1998-11-23)
Scalar, baryon and vector-current densities in coordinate and momentum space are calculated within a relativistic mean-field model. The role of the low components of the bound nucleon wave function is investigated in detail ...

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 ...

Reorganization energies for charge transfer reactions in binary mixtures of dipolar hard sphere solvents: A Monte Carlo study
(AIP Publishing, 1998-12)
We study the behavior of the reorganization energy for simple charge transfer reactions in mixtures of dipolar hard sphere fluids by Monte Carlo simulation. The static dielectric constants of the solvents are also obtained ...

Accidental degeneracy and hidden symmetry: Rectangular wells with commensurate sides
(American Association of Physics Teachers, 1998)
Two-dimensional quantum square wells and rectangular billiards with commensurate sides are simple systems which exhibit accidental degeneracies. We show that a recent analysis for square wells can be similarly ...

A Hartree-Bose mean-field approximation for IBM-3
(Springer Nature, 1998)
A Hartree-Bose mean-field approximation for the IBM-3 is presented. A Hartree-Bose transformation from the spherical to the deformed bosons with charge-dependent parameters is proposed which allows bosonic pair correlations ...

Steady state of a fluidized granular medium between two walls at the same temperature
(American Physical Society, 1998)
The steady state of a low-density gas of inelastic hard spheres confined between two parallel walls at the same temperature is studied. Because of the dissipation in collisions, the state is not uniform but highly inhomogeneous ...
