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 ...

Description of continuum structures in a discrete basis: Three-body resonances and two-nucleon decays
(SciPost, 2020)
Weakly bound and unbound three-body nuclei are studied by using the pseudostate method within the hyperspherical formalism. After introducing the theoretical framework, the method is applied first to the 9Be nucleus, ...

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. ...

Coulomb breakup in a transformed harmonic oscillator basis
(American Physical Society, 2006-05-10)
The problem of Coulomb breakup in the scattering of a two-body loosely bound projectile by a heavy target is addressed. A basis of transformed harmonic oscillator (THO) wave functions is used to discretize the projectile ...

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 ...

Core excitation effects in the breakup of halo nuclei
(American Institute of Physics, 2012)
The role of core excitation in the structure and dynamics of two-body halo nuclei is investigated. We present calculations for the resonant breakup of 11Be on protons at an incident energy of 63.7 MeV/nucleon, where core ...

Core excitations in the structure and reactions of halo nuclei
(EDP Sciences, 2014-03-20)
We analyse the resonant break-up of halo nuclei including possible excitations of the core both in the structure of the halo nucleus and in the reaction dynamics. The structure of the halo nucleus is treated in the ...

Particle motion in a deformed potential using a transformed oscillator basis
(American Physical Society, 2012)
The quantum description of a particle moving in a deformed potential is investigated. A pseudostate (PS) basis is used to represent the states of the composite system. This PS basis is obtained by diagonalizing the system ...
