Abstract

The time-dependent close-coupling method is used to study the single photon double ionization of C²⁺ in support of possible experiments at FLASH/DESY using an EBIT. Energy and angle differential cross sections are calculated to fully investigate the correlated motion of the two photoelectrons. Single energy differential as well as total cross sections are calculated for different incident photon energies in the range of 125–225 eV. Good agreement is found between our results and available R-matrix results for the double ionization of C²⁺. The study is also extended to the double photoionization along the Be-like isoelectronic sequence (Be-F⁵⁺), where good agreement is found when compared with available theoretical calculations and experimental measurements.
