    "abstract": "Considering the nuclear motion, the authors give out the nonrelativistic\nground energy of a helium atom by using a simple but effective variational wave\nfunction with a flexible parameter $k$. Based on this result, the relativistic\nand radiative corrections to the nonrelativistic Hamiltonian are discussed. The\nhigh precision value of the helium ground energy is evaluated to be -2.90338\na.u., and the relative error is 0.00034%.",
