A two-channel ?-dependent n-α interaction potential is obtained by diagonalizing the corresponding Schrödinger equations by a similar transformation. The n-α elastic scattering cross section, expressed in terms of potential parameters, is fitted by low-energy scattering data.The results are compared with the previous results.

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.
