Abstract

We construct the zeroth approximate wavefunctions using Slaters determinants, calculate energy levels and their wavefunctions of a Helium atom in exited states, and discuss its ground energy level and ground wavefunction.

Key words： Slaters determinants; degenerate perturbation theory; helium atom
