Finite-element calculations of the antiprotonic helium atom including relativistic and QED corrections
- Department of Physics, Stockholm University, Box 6730, S-11385 Stockholm (Sweden)
A recently developed extension to a three-dimensional finite-element Schr{umlt o}dinger equation solver in the total angular momentum representation was used to calculate the energy-level spectrum and wave functions for antiprotonic helium system. The accuracy of the numerical method was analyzed. Relativistic and QED corrections to the energy levels were calculated in the main order. Excellent agreement was reached between relativistically corrected wavelengths and recent experimental data. Radiative transition probabilities and lifetimes were calculated and compared with other calculations as well as with experiment. {copyright} {ital 1997} {ital The American Physical Society}
