Abstract

The adibatic potential in the layer semiconductor GaSe is considered taking into account the Davydov splitting of the bands. It is shown that in the case of electron—phonon interaction which is responsible for the Jahn‐Teller pseudoeffect, distortions are possible either normal to layers or along the layers, depending on the parameters of the electron and phonon subsystems.
