Abstract

For the plasma with an acoustic perturbation, the temperature and density changes due to acoustic perturbation were calculated from the experimentally measured acoustic pressure values. Acoustic modulation of temperature, density and pressure is not more than 0.1% of the average values. The vibrational velocity of molecules is hundreds of times less than the root-mean-square velocity, but because of the collective effect of a big quantity of molecules and the selected direction of vibrations, it is the vibrational velocity that determines the creation of acoustic superlattices in the plasma. Thus, in acoustoplasma, acoustic superlattices of particle velocities and momenta are created, rather than pressure and density ones.
