✦ Synopsis

Experimental data have been analysed concerning the angular distribution and the muon conversion rate from prompt fission fragments. It is only possible to explain the data on account for the angular anisotropy arising due to the alignment of the fragments, and the forward-back asymmetry which is brought about by the translational velocity of the fragments. The analysis clearly shows the fraction of the E2 component with the intensity of 10-15% in the hard domain of the radiative spectrum of the fragments. A possibility of direct muon emission due to shake-off brought about by the neck rupture is also discussed.
