Abstract
We investigate the radiative decay of the axion into two photons in an exte rnal electromagnetic field to one loop order. Our approach is based on the world-line formalism, which is very suitable to take into account the exter nal field to all orders. Afterwards we discuss how the calculation could be generalized to finite temperature.
