| Abstract: | By using the bosonization transformation, the energy spectrum of the antiferromagnetic chain are discussed. Under the condition of considering the interaction between lattices, it is pointed out that there exists spin Peierls transition in a special region of the strength of distortion. The relationship between the energy density of the ground state and the strength of distortion is obtained. |
