Abstract
The possibility of cooperative spontaneous two-photon emission of an e xtended radiators system and the influence of the external thermal ele ctromagnetic field on the spontaneous emission rate, in such a system, are investigated. It is concluded that, in an external electromagneti c field, the two-photon cooperative emission rate increases significan tly. The importance of this effect on the emission of gamma rays from inverted long-lived isomers triggered by X-ray thermal fields, is emph asized.
