We discuss the results of the calculation of the photoionization with de-excitation of excited He and helium-like ions Li+ and B3+ at high but nonrelativistic photon energies ω . Several lower 1S and 3S states are considered. We present and analyze the ratios of the cross sections of photoionization with de-excitation, , and of the photoionization with excitation, . The dependence of on the excitation of the target object and the charge of its nucleus is presented. In addition to theoretical interest, the results obtained can be verified using long-lived excited states such as 23S of He.
