The magnitude of the powder spin susceptibility of an optimally doped superconductor HgBa2CuO4+δ (Hg1201) in the normal state is found to be nearly the same as that of La2-xSrxCuO4 near the optimally doped level. The Stoner enhancement factor of Hg1201 is larger than that of La2-xSrxCuO4. The magnitude correlation of the Stoner enhancement factor is inconsistent with the effect of the recent theoretical Coulomb repulsion between 3d electrons and that of the superexchange interaction of a charge transfer type.
