The present work studies aspects of the electronic correlation in confined H$^{-}$, He and Li$^+$ atoms in their ground states using the informational entropies. In this way, different variational wavefunctions are employed in order of better take ac

The correlation function quantum Monte Carlo (CFQMC) approach is employed to study the energy spectra of confined quantum systems. This method, applied originally to determine rovibrational eigenenergies of molecules, is utilized here to calculate th

We propose a two-step genetic algorithm (GA) to fit potential energy curves to both ab initio and spectroscopic data. In the first step, the GA is applied to fit only the ab initio points; the parameters of the potential so obtained are then used in
