We are grateful to Professor Isidore Last and to Professor Uzi Kaldor for stimulating discussions. We are indebted to the Inter University Computation Center (IUCC) and to the Computation Center at Tel Aviv University for granting computation time and for excellent service. This research was supported by the Volkswagen Foundation and by the Israeli-German binational James-Franck program at Tel Aviv University for laser-matter interaction.

N2 - We advance an approach for the study of multistate dynamics of low Rydberg excitations in XeArN/Xe*(3P1)ArN/ Xe+ArN clusters on the time scale of nuclear motion, as explored by pump-probe neutral-to excited-to positive ion (NEEXPO) femtosecond spectroscopy. The dynamics of the Xe*ArN (N = 54) cluster induced by charge expansion inferred from the calculation of NEEXPO signals at different probe energies, manifests the lifetime τ1 ≃ 100 fs for the initial formation of the 'bubble', an intracluster vibrational energy redistribution (IVR) lifetime τI/e ≃ 5.0 ps and an IVR completion time τc ≃ 8-10 ps, which corresponds to the bubble equilibration.
