On the possibility of the X and gamma graviton discovery

The possibility of discovering X and gamma gravitons in the Universe is considered. It is supposed that the object of non-equilibrium molecular and nuclei has been formed in the result of a certain catastrophe (such as the primary explosion with the formation of the Universe). The most probable relaxation process for a rather dense object is the gravitation (bozon) avalanche. The number of gravitons irradiated by the object with the power of 1055 ergxs-1 at the distance of 1027 cm, is estimated. It equals 107 gravitonxs-1xcm-2. The conclusion is made that the modern technique of the Moessbauer experiment can be used for searching gamma-gravitons
