摘要	It is shown that the resonant frequency omega(c)* of a magnetopolaron bound to a Coulomb impurity in a GaAs/Ga1-xAlxAs quantum well is lower than that of longitudinal optical (LO) phonons owing to the effect of the Coulomb potential. Using MacDonald method to treat the Coulomb potential we come to the conclusion that omega(c)* is really below the frequency of LO phonons but not ''pinning'' at a frequency near that of TO phonons.
