Abstract
Two-dimensional patterns of angle-resolved photoemission are measured on Kish graphite for s-polarized synchrotron radiation. Very wide acce ptance cone allowed us to discuss the photoelectron intensity variatio n up to second Brillouin zone(Ba) in detail. Observed symmetry-broken patterns are theoretically discussed. It is found that an interference of photoelectron waves from non-equivalent sites provides imbalance i n different BZs and the gross feature tells us the symmetry of the ini tial state.
