摘要：

The energy level spectrum of antiprotonic helium was calculated with a newly developed three-dimensional finite-element Schrodinger equation solver in the total-angular-momentum representation. A small partition of the full coupled equation problem was found to give converged, accurate results. The calculated wavelengths agree with recent experimental results within 50 ppm. Relativistic corrections are estimated.
