On stimulated VUV emission of atomic helium in a Bose–Einstein condensate. 2

The scenario of the experiment on observation of stimulated VUV emission at a wavelength of 62 nm from metastable states of helium atoms in a Bose–Einstein condensate moving along an extended quantum-well trap is further considered taking into account the asymptotic behaviour of the current value of the stimulated emission cross section. Quantitative estimates are presented.
