  The decay dynamics of photoexcited rare gas cluster ions

  摘要：

  The kinetic energies of fast neutrals ejected from photoexcited rare gas cluster ions have been measured for the following systems: Arn+, Krn+, Xen+ at two photon wavelengths: 355 and 532 nm, and for n in the range 2–19. New data are presented for xenon at both wavelengths, and for argon and krypton cluster ions at 355 nm. For argon and krypton cluster ions at 532 nm, new data have been recorded which are more accurate than those presented previously. A Monte Carlo model of the experiment has been used to simulate the kinetic energy releases and also to investigate variations in the scattering anisotropy parameter (β) as a function of photon energy and cluster composition and size. Significant fluctuations in β are observed, and these are attributed to a combination of structural variation and changes to the nature of the central chromophore. For small cluster ions the kinetic energy release data show evidence of being influenced by the final spin-orbit state of the atomic ion. Overall, there is a gradual decline in kinetic energy release as a function of increasing cluster size; however, there are marked variations within this trend. For all three rare gas systems the results show that the primary response to photoexcitation is the ejection of a single atom with a high kinetic energy on a time scale that is short compared with the rotational period of a cluster.

  Collision-induced reaction of Ar+n (n=2−15) with Kr was studied at collision energies from 0.1 to 2.0 eV (center-of-mass) by means of a tandem mass-spectrometer equipped with octopole ion guides. The reaction was found to proceed via Ar-atom evaporation from Ar+n, charge transfer from Ar+n to Kr or fusion of Ar+n with Kr. The absolute cross sections for these processes were measured as functions of
