Abstract
Photoemission spectra of single crystalline Bi3.6Pb0.4Sr3Ca2.4Er0.7CU4 O16 have been measured in the photon energy range 20 eV < hnu < 100 eV both above and below the superconducting transition. The variation wi th photon energy in the intensity of structure close to the Fermi ener gy suggests that these states are of dominant O 2p atomic character bo th below and above T(c). The symmetry of the states is investigated by varying the polarisation of the incident radiation relative to the sa mple surface. Again there are no indications of changes at T(c).
