The band dispersions with the dx2-y2 - wave like gap opening are observed without being hindered by surface state and CuO chain band due to bulk-sensitivity and/or matrix element effect at hv = 6:994 eV. The momentum-dependence of the superconducting gap exhibits a nonzero minimum of ~12 meV along the (0,0)-(pi,pi) line. In addition, the unusual suppression of the quasiparticle coherence is observed at T/Tc > 0.5—0.7.
