We find a general expression for the one-loop self-energy function of neutral -meson due to intermediate state in a background magnetic field. The pion propagator used in this expression was given by Schwinger; it is valid for arbitrary magnitudes of this field. Restricting our study to weak fields, we calculate the decay rate , which changes negligibly from the vacuum value.
