The total and partial photoelectron yield spectra of all the trivalent rare‐earth ions in the 4 d giant resonance region are calculated with full multiplet effects. The decay processes are treated as coherent processes following photoexcitation. The results reproduce the over all features of experiments. It is obtained that the character of the giant‐absorption is different between the light and heavy rare‐earths. The multiplet effects play an essential role in the decay processes.
