On the spacing of the quasi-Landau resonances
Simple analytical expressions for the spacing between the quasi-Landau resonances, covering the whole energy range are derived. The expressions are obtained in a first-order WKB approximation considering them m=0 spinless electron to move in the z=0 plane. In addition, the authors show a crossing over of the spacing at negative energies and that the spacing is not very sensitive to the presence of a centrifugal barrier.
