Two-quantum-induced energy release of isomeric nuclei

The possibility of using some long-lived isomers with a high specific content of the energy of metastable states (~10⁷ J g^-1) as a new type of nuclear fuel is analysed. The analysis based on the model of a stimulated two-quantum radiative transition in the field of counterpropagating gamma waves between Bragg mirrors describes pulsed and continuous processes of the energy release of isomers and gives the criteria for their stability.
