Abstract
Consider an interstellar cloud that occupies the region V ?R3, bounded by the known surface ?V, and assume that the scattering cross sections and the total cross section are also known. Then, we prove that it is possible to identify the source q = q(x, t) that produces UV-photons inside the cloud, provided that the UV-photon distribution function arriving at a locationx, far from the cloud, is measured at timest0,t1 =t0+ . . . ,tJ =t0 +J
