摘要：

Particle-hole (p-h) mixing is a fundamental consequence of the existence of a pair condensate. We present direct experimental evidence for p-h mixing in the angle-resolved photoemission (ARPES) spectra in the superconducting state of Bi2Sr2CaCu2O8+delta. In addition to its pedagogical importance, this establishes unambiguously that the gap observed in ARPES is associated with superconductivity.
