Abstract
Surface phonon spectra from Ta/Al Fibonacci multilayers are studied vi a Brillouin scattering. Determination of the frequency positions of th e Rayleigh wave and the intensity dip corresponding to the longitudina l threshold has enabled us to extract two effective elastic constants C44 and C11 of the whole structure. The 22.6% enhancement of the shear modulus is found in our experiment.
