Cyclotron resonance (CR) measurements on a single crystal of LaSb have been performed in the temperature range from 1.6 K to 40 K in the frequency range from 50 to 190 GHz. We have observed three CR absorption lines at low temperature. For magnetic fields parallel to the [100] direction, the determined effective masses are 0.20 ± 0.02m0, 0.17 ± 0.02m0, and 0.45 ± 0.04m0, which correspond to the α-branch, the β-branch, and the γ-branch, respectively.
