摘要：

The electron-phonon interaction in one-dimensional electronic systems, in the half-filled tight binding form of the electron momentum distribution function, within the random-phase approximation, leads to instability of the systems, if the strength of the electron-phonon coupling constant exceeds π2/8. © 1979.
