Hybrid resonances are investigated in a quantizing magnetic field in semiconductive BiSb alloys. The measurements are carried out at 1.6 K at frequencies ranging between 120 and 70 GHz with the magnetic field being parallel to the binary axis. It is found that above a definite measuring frequency hybrid resonances can be detected, the occurrences and the field location of which are in effect determined by the redistribution of charge carriers between the component surfaces of the parted Fermi surface in the quantizing magnetic field. The discussion of the results allows the determination of the spin splitting parameter, which is found to be G 2 = 0.9. A quadratic relation between energy and momentum gives good agreement between theory and experiment.
