Title: Calculation of the thermodynamic parameters and the degree of ionization of argon at sonoluminescence

The results of the numerical simulation of the behavior of a system consisting a spherical bubble filled with gaseous argon and surrounded by water under the impact of an external periodic pressure are presented. It is shown that, under typical conditions for the experimental investigation of single-bubble sonoluminescence in such a system, conditions are created for its thermal ionization near the time instant of the maximum compression in the gas. This proves one of the main provisions of the polarization model of sonoluminescence.
