Abstract The energy levels of a positronium negative ion are calculated
directly from the Schrödinger equation. After removing the
translational and rotational degrees of freedom, only three internal variables are involved in both functions and equations.
The singularity of the solution is eliminated by choosing the right internal variables, and the series in calculation converges very fast.
