Superradiation under bragg diffraction conditions

The kinetics of superfluorescence under anomalous gamma-quanta penetration conditions are considered. It is shown that when the Bragg condition is satisfied the superfluorescence mode is similar to the singlemode condition with certain characteristic values of the parameters. The direction of propagation of the Borrmann mode is a distinct direction in the crystal. The radiation pattern of the radiation will be determined by the intersection of the diffraction pattern of the working material and the Bragg diffraction cone. The use of high-multipole working transitions may reduce the generation threshold by an order of magnitude.
