Insight Into

Abstract Negatively charged tin clusters offer a broad range of decay products, as observed after electron-cluster interactions [S. König, M. Wolfram, S. Bandelow, G. Marx, L. Schweikhard, Eur. Phys. J. D 72, 153 (2018)]. To get further insight into their decay pathways, size and charge-state selected clusters Snn- and Snn2- were photo-excited at the ClusterTrap setup by 532 nm Nd:YAG laser pulses. For small mono-anionic precursor clusters containing up to n ≃ 45 atoms, Snn-7- and Snn-10- are observed as preferred ionic fragments. For bigger clusters a transition to neutral monomer evaporation was found. In the case of di-anionic precursors, preferred decay products are Sn10- and Snn-10-, indicating fission similar to the case of the group 14 neighbor element lead [S. König, A. Jankowski, G. Marx, L. Schweikhard, M. Wolfram, Phys. Rev. Lett. 120, 163001 (2018)]. Furthermore, doubly charged fragment clusters such as Snn-72- are observed, originating from break-off of neutral heptamers Sn7, a behavior which has not been observed previously for di-anionic clusters.

It is well known that in the initial energy spectra of hydrocarbon fragment ions formed by electron impact, satellite ion groups occur which are believed to be mainly due to the fragmentation of doubly charged ions into two singly charged fragments. By using an electron energy of 150 eV a new type of satellite was observed in the initial energy spectra of C1Hk+ and C2Hl+ fragment ions from hydrocarbons with three and more carbon atoms. The n-paraffins were investigated systematically up to n-decane. Because the initial energy of these satellites is nearly twice the initial energy of the already well known “first” satellites, it is suggested that these newly discovered “second” satellites are due to an analogous fragmentation process of the typeA+++→B+ + C++.Therefore, a careful search was made for the corresponding doubly charged fragment ions of high kinetic energy. Well pronounced satellite groups of doubly charged fragment ions were, indeed, found. Their momentum approximately equals the momentum of the corresponding “second” satellites of singly charged fragments, which supports the suggested mechanism.
