Abstract

The large intensity of the resonance at Q=(π,π) was studied and found to be consistent with the small value of the total momentum and frequency integrated intensity of the resonance peak, and with the fact that the magnetic part of the condensation energy is only a small fraction of J. It was observed that the spin-fermion coupling g is of the order of 1 eV.
