• Cyclotron absorptions in n- and p-type PbTe recently observed by Nii are analysed under classical skin effect conditions. When the values of d.c. magnetic field corresponding to peaks are plotted against the field directions, a close fit is obtained between the calculated and observed results on an assumption of a set of <111> ellipsoids of revolution model for the both conduction and valence band extrema. From the best fit m_t=0.024m_o and 0.031 m_o for the transverse effective masses and K=m_l/m_t=9.8 and 12.2 for the anisotropic mass ratios are abtained for each band. The observed absorption curve shows weak structures at low magnetic field. They are supposed to be due to the second harmonics of Azbel'. Kaner cyclotron resonance. However it is unnecessary to introduce other bands to explain the experimental results. The applicability of the classical magneto-ionic theory is examined by calculating the power absorption coefficient and the penetration depth as a function of d.c. magnetic field.
