Abstract.
Electron-Ion-Coincidence (EICO) and Multiple-Ion Coincidence Momentum Imaging (MICMI) measurements were carried out for deep inner-core excited rare-gas clusters. From MICMI measurements, momentum distributions and time-of-flight (TOF) spectra of daughter ions were obtained for the number of coincident signals, Ncoin, up to 8. The TOF spectra for Ncoin larger than 2 indicate that only singly-charged ions are the products of Coulomb explosion. The observed fragmentation pattern and the momentum distribution of singly-charged daughter ions reveal that the heavier ions have smaller momentum than the monomer ions. This suggests that the heavier ions are produced in the central part of clusters where the Coulomb forces from the surrounding ions are more effectively canceled out. All these results are consistent with the site-dependent decay process predicted recently by us for Kr clusters.
