Double photoionization of Be-like (Be-F$^{5+}$) ions
POSTER
Abstract
The time-dependent close-coupling method is used to study the single photon double ionization of Be-like (Be - F$^{5+}$) ions. Energy and angle differential cross sections are calculated to fully investigate the correlated motion of the two photoelectrons. Symmetric and antisymmetric amplitudes are presented along the isoelectronic sequence for different energy sharing of the emitted electrons. Our total double photoionization cross sections are in good agreement with available theoretical results and experimental measurements along the Be-like ions.
