Abstract: 

Current status of 3-body Coulomb problem (negative hydrogen ion H-, helium atom, lithium ion, H2+ ion etc) will be described.Major emphasis will be given to a question of stability vs Coulomb charge and to analytic structure of the ground state energy. The existence of two critical charges with associated square-root and essential singularities, respectively, is predicted. The 2nd excited, weakly-bound state of H- is predicted as a result.Current status of 3-body Coulomb problem (negative hydrogen ion H-, helium atom, lithium ion, H2+ ion etc) will be described.Major emphasis will be given to a question of stability vs Coulomb charge and to analytic structure of the ground state energy.
