Diffraction of optical radiation on spatially ordered structures of macroparticles in a strongly nonideal thermal plasma

The first observation of the diffraction of optical radiation on ordered st ructures of macroparticles in a low-temperature thermal plasma was reported . The experiments were conducted in an air thermal plasma at atmospheric pr essure with CeO2 particles at temperatures 1800-2200 K. The parameters of t he plasma medium were determined using probe and optical diagnostics method s. The binary correlation function of the system of macroparticles was reco nstructed from measurements of the structure factor. Simulation of nonideal plasma with the parameters corresponding to experiment was performed by th e molecular dynamic method. The computed and experimental correlation funct ions were compared, and it was noted that they are in good agreement with o ne another. (C) 2000 MAIK "Nauka/Interperiodica".
