The conditions for the stability of this system are discussed as well as the methods used to achieve it. We also present the full analytical expression of the variational energy for a Chandrasekhar correlated wave function. Further, we stress the special structure concerning this ion in comparison with the other two-electron systems5 p.application/pdfengcc-by-nc-nd (c) López de Arbina, 201http://creativecommons.org/licenses/by-nc-nd/3.0/es/IonsCorrelació (Estadística)Teoria quànticaTreballs de fi de grauIonsCorrelation (Statistics)Quantum theoryBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
