The Hamiltonian for atom with two electrons is represented in the algebraic form via the quantum annihilation and creation operators, thus the algebraic method can be used to solve the problem. Here, a basic set in the algebraic form given as a set of eight-dimentional harmonic oscillator wave functions is useful for calculating, and, from other side, characterizes the Coulomb interaction wave functions, that makes the considered problem very effective to solve. This method can be developed for other more complex atomic systems such as a helium atom in a magnetic field.
