The Schrodinger equation for two-electron atoms is replaced by another equation depending on a free dimensionless parameter P. Solution of the latter equation amounts to the diagonalization of a (Pdependent) in6nite symmetric sparse matrix. The nonzero elements of this matrix are very simple and directly related to a representation of the o(4,2) algebra. Numerical results are in agreement with energy levels of the helium atom when P goes to infinity. PACS number(s): 31. 20.Tz, 31.50.+w, 34.80.i, 03.65.Fd
