On the problem of forced release of nuclear energy of longlived isomers

We consider a new type of nuclear chain reaction, namely, a reaction of ant i-Stokes radiative transitions of longlived metastable isomers triggered by quasi-equilibrium black body radiation of a dense hot plasma which relativ ely high temperature is supported in its part by absorption of gamma-photon s emitted by nuclei. As result the energy stored in metastable isomer state s is released and an intense burst of gamma-photons is emitted. Quantitativ e estimates are presented.
