Popis:	Particular cases of reflection of bulk acoustic waves from a free surface of cubic crystal, when both the plane of incidence and the crystal surface are symmetry planes, to which the polarization vectors of incident and reflected waves are parallel, have been analyzed. The conditions under which only a single bulk reflected wave (rather than two as generally) is formed at reflection are described. The accompanied reflected wave (bulk or localized) disappears, so that the reflection turns out degenerate. Either a pure reflection (the incident and reflected waves belong to the same acoustic branch) or a conversion reflection (the given waves belong to different branches) are formed.
