Resumen:
The angularly correlated basis functions proposed by Gasaneo andAncarani (Phys Rev, A 77:012705, 2008) are used to construct approximated wavefunctions,satisfying all two-body cusp conditions, for several three-body systems.The focus here is on the study of the following negatively charged hydrogen-likeions: ∞H−, 1H−, D−, T− and Mu−, the negative positronium ion Ps−, and theexotic systems e−e−(nme)+ in which one of the particles is heavier than the othertwo. Accurate results for the mean of the ground state energy and of other radialquantities are compared with those given in the literature, when available.
