N2 - An empirical formula for energy level shifts of pionic atoms is proposed. Numerical results show remarkably good agreement with experimental data. We predict energy level shifts and widths for pionic deuterium, tritium and helium. With these values, scattering lengths of π-d, π-t and π-3He are also calculated. The results are (in fm) -0.083 + 0.024 i, -0.287 + 0.028 i and 0.067 + 0.035 i, respectively.
