Effect of Bose condensation on inelastic processes in gases
Kagan Yu., Svistunov B. V., Shlyapnikov G. V.
A change in the structure of the wave function of the initial state causes the probability for an inelastic process in a Bose gas to decrease sharply upon the appearance of a Bose condensate. In a gas of spin-polarized atomic hydrogen, the result is a decrease in the rate of three-body dipole recombination. There is accordingly the possibility of observing a phase transition.
