摘要：
A new momentum-space method is developed for calculation of the strong-interaction shifts and widths in pionic atoms. The singularity connected with the Coulomb potential is treated by using the Vincent and Phatak prescription. The nuclear and atomic distances are separated in our scheme and this secures numerical stability of the calculation. The latter property makes the method a useful alternative to the earlier algorithms. Sample results for a series of light pionic atoms are shown.
