The study of structure and collision processes of three-and four-body problems has seen an
extraordinary progress in the last decades. This progress has been in part associated to the …

Hyperspherical harmonics are extremely useful in nuclear physics and reactive scattering
theory. However, their use has been confined to specialists with very strong backgrounds in …

This book describes the generalized Sturmian method, which offers a fresh approach to the
calculation of atomic spectra. Generalized Sturmians are isoenergetic solutions to an …

The computational techniques needed to generate a two-body Generalized Sturmian basis
are described. These basis are obtained as a solution of the Schrödinger equation, with two …

Sturmian basis sets are increasingly finding applications to the description of atomic and
molecular structure, because of their mathematical properties and their flexibility regarding …

In this paper we discuss the optimization of Sturmian basis functions by studying bound
atomic systems within the configuration interaction method. Our investigation clearly shows …

An accurate theoretical description of photoionization processes is necessary in order to
understand a wide variety of physical and chemical phenomena and allows one to test …

In this study, we address the problem of a C60 endohedrally confined hydrogen molecule
through a configuration–interaction approach to electronic dynamics. Modeling the …

We present a configuration-interaction (CI) method based on Sturmian functions. The
components of this CI basis are the solutions of a two-body Sturmian eigenproblem, where …

Effects of finite nuclear size and finite nuclear mass are investigated for muonic atoms and
muonic ions embedded in the Debye plasma. Both nuclear charge radii and nuclear masses …
