The optoacoustic method of determination of the Kapitza resistance

The theory of the optoacoustic (OA) generation of the first and second sounds in the He-II which contacting with solids has been proposed. The two contours structure of the specters the both sounds have been shown. The seconds contours are connected by the presence of the interaction between these acoustical modes and corresponds to a slow first sound and to the fast second sound. The two basic opportunities of determination of the Kapitza resistance from the results the ОА of experiments are founded.
