Formation of microparticles initiated by XeCl laser radiation photolysis of Mo(CO)6 mixed with buffer gas
was studied. It was shown that micron-sized heavy objects (microparticles) of little mobility were formed
and scattered the beam of the He-Ne probe laser. The microparticle mass and size were determined from
probe laser beam scattering. The average density of microparticle was estimated (ρ ≈ 0.1 g·cm-3).
