The energy levels in D waves for the parahelium and the orthohelium with both odd and even parity are calculated directly from the Schrodinger equation. After removing the;translational and rotational degrees of freedom, only three internal variables are invoked in both the functions and the equations. The appropriate internal variables are chosen to remove the singularity in the solutions and to improve the convergence of the series in calculation.
