Scenario of the experiment on gamma-ray amplificationupon stimulated transitions in isomeric nucleiin a Bose—Einstein condensate

The scenario of the experiment on the amplification of gamma rays upon stimulated transitions from metastable states of isomeric nuclei in a Bose–Einstein condensate (BEC) is presented. The experiment involves the successive transport of atoms along the so-called quantum conveyer. It is shown that if the excess broadening of the gamma-ray emission line is eliminated, the total gain G > 1 can be achieved despite the presence of negative factors such as the 'laser lethargy', spontaneous decay of metastable states, etc.
