Abstract
We demonstrate that the E vs k dispersion in the superconducting state extr acted from momentum-distribution curves differs qualitatively from the trad itional dispersion extracted from energy-distribution curves. This occurs b ecause of a combination of many-body effects and the presence of an energy gap, along with the associated coherence factors. Analysis of such momentum -distribution-curve dispersions can give important information on the micro scopics of high-temperature superconductors.
