STM/STS studies have been carried out on the ( 110) and (100) surfaces of YBa2Cu3Oy single crystals with a superconducting transition temperature Tc of about 90 K. In most cases on the (110) surface, the spectra of the quasi-particle excitations in the superconducting state exhibit characteristics o
