Abstract
Data are presented to show that the magnetoabsorption of Bi in the infrared is due to direct interband transitions between Landau levels rather than from de Haas-van Alphen type oscillations of the Fermi level as previously hypothesized. These new data permit a more accurate determination of the energy gap and yield a value of 0.024 eV for this energy.Keywords
