We have obtained the alpha- alpha interaction for the coupled channels in which the internal structure of the alpha particles is approximately represented by a two-state system.In this model, the alpha-alpha interaction is represented by a 3*3 matrix. By using an unitary transformation, we obtain an exact expression for the phase shift in terms of the potential parameters which is determined from the two-body scattering data.

We use the quasiparticle approach and the method of the equation of motion to study a one-dimensional solid with electron-phonon interaction.After transforming to a moving frame, an energy gap in the single electron energy spectrum with a width at v=0;△=16Efe^-1/λ is obtained, which has the same form as in pairing theory. We also obtain a state in which the electrons will move with the phonons in an organized way. Thus the conductivity will increase extrodinary if v is sufficiently small. This result agrees with the experimental phenomenon, which was observed recently in some one-dimensional organic solid.
