摘要：

We have studied momentum distribution of photoemission intensity around the Fermi surface of Bi2Sr2CaCu2O8+delta (Bi2212) high T-c superconductor by angle-resolved photoemission. The line shape of the energy distribution curves show a spectral function A(k,omega) expected for a non-Fermi liquid behaviour. The Fermi surface contour in the 'even symmetry' reveals the suppression of spectral weight due to coupling with joint incommensurate charge density wave (ICDW) at q(- 0.4 pi,0.4 pi) in the diagonal direction and the spin density wave (SDW) at G(pi,pi). Additional spectral weight is found at (0.6 pi,0.6 pi) due to scattering of electrons with SDW at optimum doping as revealed by constant energy contour in 'odd symmetry'.
