Direct interband magneto-optical transitions have been observed in pure n-type InSb at liquid-helium temperature using magnetic fields up to 96.5 kG. The theory of the magnetic levels in the valence and conduction bands at the zone center is carried out using a modification of the method of Luttinger and Kohn. The interaction between conduction and valence bands has been treated exactly, and the effect of higher bands to order k 2. Selection rules have been evaluated for both allowed (Δ n= 0,− 2) and warping-induced (Δ n= 2,±4,− 6) direct valence-to-conduction-band transitions. Comparison of theoretical with experimental spectra (using circular and plane-polarized light in the Faraday and Voigt configurations, respectively) has shown good agreement for the magnetic field in the [110] and [100] crystal directions. The following band parameters are obtained: conduction-band effective mass m c= 0.0145 m 0: light-hole effective mass m l. h.= 0.0160 m 0; heavy-hole effective masses m h. h.[100]= 0.32 m 0, m h. h.[110]= 0.42 m 0, m h. h.[111]= 0.44 m 0.
