Abstract Particle-hole ({ital p}-{ital h}) mixing is a fundamental consequence of the existence of a pair condensate. We present direct experimental evidence for {ital p}-{ital h} mixing in the angle-resolved photoemission (ARPES) spectra in the superconducting state of Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}}. In addition to its pedagogical importance, this establishes unambiguously that the gap observed in ARPES is associated with superconductivity. {copyright} {ital 1996 The American Physical Society.}
