In terms of diffusion (for the space) and Fokker-Planck (for photon energy) approximations a fast converging series describing the supernova envelope hard X-ray emission (hν < 1 MeV) was obtained assuming the central source of hard photons of any type. Compton scattering on cold electrons follwed by the recoil effect and photoabsorption are the main processes which determine the spectrum's shape. An opportunity of envelope geometry investigation during the observations of direct emission γ-quanta is also considered.
