Query: Hadronic Cross Sections in Electron-Positron Annihilation with Tagged
  Photon   Events with tagged photons in the process of electron-positron annihilation
into hadrons are considered. The initial state radiation is suggested to scan
the hadronic cross section with the energy. QED radiative corrections are taken
into account. The results for the total and exclusive cross sections are given
in an analytic form. Some numerical estimates are presented.
