The multiple ionization of Ar-core-Ne-shell clusters in intense extreme-ultraviolet laser pulses (λ∼62 nm) from the free-electron laser in Japan was investigated utilizing a momentum imaging technique. The Ar composition dependence of the kinetic energies and the yields of the fragment ions give evidence for charge transfer from the Ar core to the Ne shell. We have extended the uniformly charged sphere model originally applied to pristine clusters to the core-shell heterogeneous clusters to estimate the amounts of charge and energy transfers.
