On Dalgarno and Lewis Perturbation Theory for Scattering States
Paolo Amore, Francisco M. Fernandez
We apply the method of Dalgarno and Lewis to scattering states and discuss the choice of the unperturbed model in order to have a convergent perturbation series for the phase shift…

Variational collocation on finite intervals
Paolo Amore, Mayra Cervantes, Francisco M. Fernández
In this paper we study a new family of sinc--like functions, defined on an interval of finite width. These functions, which we call ``little sinc'', are orthogonal and share many o…

Application of the Asymptotic Iteration Method to a Perturbed Coulomb Model
Paolo Amore, Francisco M. Fernandez
We show that the asymptotic iteration method converges and yields accurate energies for a perturbed Coulomb model. We also discuss alternative perturbation approaches to that model…
