Abstract: | We demonstrate rather interesting manifestations of co-existence of resonance features in characteristics of the photoionization
of 3d-electrons in Xe, Cs and Ba endohedral atoms. It is shown that for all of the considered atoms the reflection by the fullerene
shell of photoelectrons produced by the 3d subshell photoionization affects greatly partial photoionization cross-sections of 3d
5/2 and 3d
3/2 levels and respective angular anisotropy parameters, both dipole and non-dipole adding to all of them additional maximums
and minimums. The results obtained demonstrate distinctive differences between the three atoms. The calculations are performed
treating the 3/2 and 5/2 electrons as electrons of different kinds with their spins “up” and “down”. The effect of the C60 shell is accounted for in the frame of the “orange” skin potential model. It is essential that in the considered photon frequency
region the presented resonance features are not affected by the C60polarization.
