Resonance scattering of a monochromatic transverse acoustic wave of the Rayleigh polarization from an isotop defect layer is considered. The phase velocity $c$ of the incident wave along the defect plane is assumed to lie in the interval c_l>c>c_t. It is shown that the phenomena of the total reflection of the transverse wave from the thin plane defect and the total transition take place for the frequencies depending on the defect parameters. The former can always be observed for a heavy defect and never for a light one. The latter is possible for both light and heavy defects.
