Analytic evaluation of Franck-Condon integrals for anharmonic vibrational wave functions
(American Physical Society, 1999)
The problem of calculating Franck-Condon overlap integrals in molecular transitions between vibrational states in different electronic configurations is addressed. An exact and easily applicable analytical expression is ...

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. ...

On the relation between algebraic and configuration space calculations of molecular vibrations
(Elsevier, 1996-03)
The relation between algebraic and traditional calculations of molecular vibrations is investigated. An explicit connection between interactions in configuration space and the corresponding algebraic interactions is established.

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 ...

Comment on “Boson-realization model for the vibrational spectra of tetrahedral molecules”
(American Physical Society, 1997)
An algebraic model in terms of a local harmonic boson realization was recently proposed to study molecular vibrational spectra [Zhong-Qi Ma et al., Phys. Rev. A 53, 2173 (1996)]. Because of the local nature of the bosons ...

A general algebraic model for molecular vibrational spectroscopy
(Elsevier, 1996)
We introduce the anharmonic oscillator symmetry model to describe vibrational excitations in molecular systems exhibiting a high degree of symmetry. A systematic procedure is proposed to establish the relation between the ...

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 ...

Consistent baryon mapping of quark systems
(American Physical Society, 1994)
We present a new and consistent mapping of colorless three-quark clusters onto colorless triplet fermions (baryons) and test it in the context of a three-color extension of the Lipkin model. For systems with two triplets ...
