Abstract: 
The theory of photo recombination is reviewed and cross sections for radiative and dielectronic recombination and for interference between both processes are derived by an expansion of the T-matrix in low order. In order to demonstrate the interference effects, KLL-photo recombination cross sections are calculated for hydrogen-and helium-like uranium ions. The radiative recombination cross sections are obtained with a multipole expansion for the radiation field leading to an increase of the cross sections by a factor of 2 compared with calculations in the dipole approximation. The effect of interference is found to be strongest in hydrogen-like very heavy ions.
