Abstract
A four-band model Hamiltonian is used to evaluate the BCS-coherence fa ctors which yield the results for low-frequency electromagnetic respon se and NMR data in the superconducting state. It is found that the ape x oxygen ion dominantly contributes to the low frequency properties of high-T-c superconductors which have been evidenced elsewhere as favou ring d-wave pairing.
