Fragmentation in collisions of Na-9(+) clusters with Cs atoms

We have evaluated charge transfer, excitation and fragmentation cross secti ons in N-9(+) + Cs collisions using a molecular close-coupling formalism an d a postcollisional rate-equation model. The calculated charge transfer cro ss sections are in good agreement with recent experimental measurements bel ow v = 0.04 au. We show that the relative abundance of the different fragme nts depend critically on the cluster temperature and the spectrometer time- of-flight window.
