Interaction of size-selected stored anionic tin clusters with electrons — •Markus Wolfram, Steffi Bandelow, Alexander Jankowski, Stephan König, Gerrit Marx, and Lutz Schweikhard — Felix-Hausdorff-Straße 6, Institut für Physik, Greifswald, Deutschland

At the ClusterTrap-setup [1] size-selected mono-anionic tin clusters Sn_n¹⁻, n = 7 - 75, are stored simultaneously with electrons in a Penning trap to produce poly-anionic clusters by electron attachment [2].

In addition to doubly and triply charged clusters with the size of the precursors, fragments such as Sn_n−7¹⁻, Sn_n−10¹⁻ or Sn_n−15¹⁻ are observed [3]. The latter come along with the clusters Sn₁₀¹⁻ and Sn₁₅¹⁻, probably due to fission as in the case of the group-14 neighbor element lead [4].
