Calculations of electron–longitudinal optical phonon scattering rates between Landau levels in semiconductor heterostructures with a magnetic field applied parallel to the direction of confinement are reported. We have found that the scattering rate shows strong oscillations as a function of the applied field, depending on the configuration of the energy states in the structure. In the limit $\overrightarrow{B}0,$ the expressions for the intersubband scattering rate between Landau levels reduce to those obtained in the case of two-dimensional subbands at $B=0\mathrm{}\mathrm{T}.$
