title: Effect of symmetry distortions on photoelectron selection rules and spectra of Bi2Sr2CaCu2O8+delta.
abstract: We derive photoelectron selection rules along the glide plane in orthorhombic Bi2Sr2CaCu2O8+delta (Bi2212). These selection rules explain the reversed intensity behavior of the shadow and the main band of the material as a natural consequence of the variating representation of the final state as a function of k(parallel). Our one-step simulations strongly support the structural origin of the shadow band but we also introduce a scenario for detecting antiferromagnetic signatures in low doping.
