Cyclotron effective masses of two extremal orbits on the third zone electron arm in lead have been studied for the symmetry direction (110) using the de Haas-van Alphen effect. The temperature dependence of the amplitudes of both the node and antinode for the well known 42.5 cycle beat pattern has been analysed to evaluate each of the two individual cyclotron effective masses, i.e. mc* and mn* of the gamma c and gamma n oscillations, respectively. Here gamma c and gamma n denote the dHvA oscillations arising from the larger and smaller extremal orbits on the electron arm, respectively. The cyclotron effective mass ratios thus determined are mc*/m0=0.539+or-0.006 and mn*/m0=0.571+or-0.007, where m0 is the rest mass of the free electron. These mass ratios are favourably compared with the ones recently determined by Onuki et al. (1977) using the Azbel-Kaner cyclotron resonance technique.
