Within the framework of the asymptotic iteration method, we investigate the exact analytical solution for pionic atom in the Coulomb field of a. nucleus. Exact bound state energy eigenvalues and corresponding eigenfunctions are determined for the case of angular momentum l ≠ 0, for which the Coulomb potential is exactly solvable. Bound state eigenfunctions solutions, which have been extremely used in applications related with molecular spectroscopy, are obtained in terms of confluent hypergeometric functions. © World Scientific Publishing Company.
