Popis: The phonon effects on a multichannel resonant-level model have been studied by a bosonization technique and canonical transformations. We found that the model can be mapped onto a single-channel Kondo model and the non-Fermi-liquid transition is modified by local electron - phonon interaction. At strong interaction, only one channel of conducting electrons is necessary in order to realize this transition and it is the phonon effects that control the behaviour of the system.
