Abstract The one-dimensional Fermion system with backward scattering has been analyzed by use of the methods of bosonization and Gaussian wave functional. We find that there exist two kinds of phase transitions in the spin density degree according to the interaction parameters: one is a Kosterlitz-Thouless type transition and the other is a first order phase transition when backward scattering becomes sufficiently strong.
