It is shown that the dipole photoabsorption cross section of almost all subshells of all atoms behaves as E−7/2 in the high-energy limit, and in most of the cases, satellite (two-electron) processes dominate. In addition, it is found that in these cases, the ratio of the satellite processes (including double ionization) to the main line does not approach a limit, but increases as E.
