Two-center resonant photoionization-excitation driven by combined intra- and interatomic electron correlations
Ionization-excitation of an atom induced by the absorption of a single photon
in the presence of a neighbouring atom is studied. The latter is, first,
resonantly photoexcited and, afterwards, transfers the excitation energy
radiationlessly to the other atom, leading to its ionization with simultaneous
excitation. The process relies on the combined effects of interatomic and
intraatomic electron correlations. Under suitable conditions, it can dominate
by several orders of magnitude over direct photoionization-excitation and even
over direct photoionization. In addition, we briefly discuss another kind of
two-center resonant photoionization with excitation where the ionization and
residual excitation in the final state are located at different atomic sites.
