Abstract

The energy levels of the metastable states of Coulombic exotic three-body systems were calculated with the non-adiabatic coupled rearrangement channel method. The resonant boundary condition of the metastable levels is taken into account. Relativistic and QED corrections on the energies were made. Excellent agreement between corrected wavelengths and experimental data was achieved. This agreement gave the best limit of the antiproton mass with 10-7 uncertainty.
