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. ...

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 ...

Configuration localized Morse wave functions: Application to vibrational transitions in anharmonic diatomic molecules
(American Physical Society, 1999)
The bound states of a Morse potential are described in terms of a basis of states that are characterized for being eigenstates of the Morse variable. These states are strongly localized in configuration space; thus they ...

Analytic description of the scattering of electrons by molecules
(American Physical Society, 1995)
The scattering of electrons by molecules is considered. The structure of the molecule is described in terms of the vibron model, which is an algebraic approach to the description of rotational and vibrational molecular ...
