The Bose–Einstein condensation ofparticles in the multicomponent environment of dilute, warm nuclear matter is studied. We consider the cases of matter composed of light clusters with mass numbersand matter that in addition to these clusters containsnuclei. We apply the quasiparticle gas model which treats clusters as bound states with infinite lifetime and binding energies independent of temperature and density. We show that theparticles can form a condensate at low temperatureMeV in such matter in the first case. When thenucleus is added to the composition, the cluster abundances are strongly modified at low temperatures, with an important implication that thecondensation at these temperatures is suppressed.
