摘要：
A new interpretation of photoemission spectroscopy data is proposed. It is based on the impurity mechanism of high-temperature superconductivity proposed earlier. The band observed near the Fermi level in this interpretation is the impurity band, and the observed large ''Fermi surface'' is the surface of the mobility edge, different in different directions. Many other details are also explained naturally.
