Abstract
Transmittance periodic oscillations are observed in GaSe and InSe on e xcitation with optical pulses. Such oscillations are explained in term s of photoacoustic generation of dilatational waves, which become reso nant within the crystal. Spectral analysis of those oscillations in sa mples of different thickness has led to an accurate determination of t he longitudinal acoustic-wave velocity along the crystallographic axis c.
