Abstract
We present a calculation of the photoabsorption and photoemission cross sections of atomic copper in the neighborhood of the $3p$ threshold employing a time-dependent self-consistent-field approximation amended to include self-energy corrections necessary for a proper description of core-hole Auger decay. The calculated spectrum includes a contribution from a shake-up satellite in the two-particle spectrum which becomes resonant at the $3p\ensuremath{-}4s$ transition energy and is in good agreement with available absorption data. We present the relevant partial cross sections in the one-particle spectrum and include a brief discussion of the absorption above the $3p$ threshold with regard to the requirements of self-consistency.
