Abstract
Detailed studies indicate a superconducting gap in the high-temperature superconductor Bi 2 Sr 2 CaCu 2 O 8 . Photoemission measurements with high energy and angle resolution isolate the behavior of a single band as it crosses the Fermi level in both the normal and superconducting states, giving support to the Fermi liquid picture. The magnitude of the gap is 24 millielectron volts.Keywords
