Fragmentation in collisions of Na9+ clusters with Cs atoms

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