Abstract
The dynamics of the fragmentation process following the recombination with low energetic free electrons was studied for Hþ 3 and Dþ 3 using a two-dimensional imaging technique. The kinematical correlation of the atomic fragments in the three-body fragmentation channel, as well as the vibrational excitation distribution of the molecular fragments in the two-body channel, could be determined. In addition, a considerable rotational excitation of the Hþ 3 and Dþ 3 ions circulating in the storage ring TSR was observed even after storage time of more than 1 min. In contrast, the heteronuclear D2H+ isotopomer possessing an electric dipole moment does not exhibit any internal excitations after 10 s of storage.
