Description

The theory of generation of photoacoustic signal by superfluid helium corresponding to general case has been proposed. The expression for parameters of this signal has been obtained. Shown that amplitude and phase of photoacoustic signal depend on thermo physics parameters of the sample, substrate and buffer gas. The simple cases are analyzed in detail. (author)
