Oscillations have been observed in the magnetoacoustic attenuation of Sb for sound propagated along the binary axis, and the magnetic field in the binary-bisectrix plane and the binary-trigonal plane. The oscillations were of sinusoidal, rather than of resonant character, even for qH, and were therefore interpreted as geometric resonances. Expressions are given for the period as a function of angle, and the data were compared with the resulting theoretical curves. Of the eight effective mass parameters necessary to evaluate the theoretical expressions, all seven of the parameters measured in a previous Shubnikov-de Haas experiment were used, and the remaining parameter was taken from the present experiment. The resulting curves are in good agreement with the data. The reciprocal effective mass tensors have been re-evaluated by using the new parameter.
