Bosonic stimulation of energetic processes

We calculate the rate for stimulated transitions with photon emission betwe en two trapped bosonic gases in thermal equilibrium, for both the box and h armonic oscillator traps in the weak interaction limit. It is shown that st imulation has a peak at a temperature characteristic of the kinetic energy of final state bosons. The problem of nuclear gamma- and beta -decay stimul ation is reanalysed and a possible method for obtaining observable results suggested. (C) 2001 Elsevier Science B.V. All rights reserved.
