Summary :

The Cooper pairing interaction in high T_c oxide superconductor is discussed in terms of an empirical expression; T_c_Dexp[1/g], gc・ω_o which was derived in our previous investigation. The dual character of this expression consisting of the phonon Debye temperature _D and electronic excitation ω_o in the mid-infrared region can be interpreted on the basis of the phonon-assisted mechanism on carrier conduction and the electronic excitation. A tunneling spectrum here presented shows certain evidence of the phonon contribution. The characteristics of the long range superconductive proximity phenomena recently reported are also may be interpreted by this mechanism.
