In this article exact solutions of a two-electron Schroedinger equation for the Coulomb potential were extended to the Fues-Kratzer-type potential: ({cflx Z}({Omega})/r) + ({cflx A}/r{sup 2}). The wave function {Psi}(r, {Omega}) is expanded into generalized Laguerre polynomials and hyperspherical harmonics. An analytical expression of two-electron systems is given for matrix elements and accurate energy eigenvalues of the excited state of {sup 1,3}S helium are calculated by using the hyperspherical harmonics method. The present results are compared with previous theoretical calculations and it is concluded that the convergence of energy eigenvalues is faster.
