The analytical expression for the absorption coecient of the electromagnetic radiation by electrons a quantum wire is obtained. We used the first-order perturbation theory. The cases of linear and circular polarization of the electromagnetic wave are investigated. The resonance character of the absorption is shown and resonant frequencies are found.
Keywords: quantum wire, electron-photon interaction, absorption coecient.
