Abstract

Bromine atoms have been attached to the surface of polyethylene single crystals and the effect of these surface masses on the longitudinal acoustic mode has been determined. As the amount of bromine is increased, the LA mode peak frequency decreases and the bandwidth increases. The observed peak frequency decrease is in good agreement with values calculated from the composite rod model.
