英文摘要	Mathematica language is used to make a program that can solve the three-body problem with variational method. Considering the nuclear motion, the nonrelativistic ground energies and the analytic wave functions of the helium atom and the helium-like ions (H1, He, Li+, Be++, B3+, C4+, N5+, O6+) are presented by using a simple effective variational wave function with a flexible parameter k. Based on these results, the influence of a finite nucleus charge radius, the relativistic and radiative corrections on the nonrelativistic Hamiltonian are discussed. The high precision values of the helium atom and the helium-like ions ground energies are evaluated.
