Imaging of metastable $\textrm{CO}_2$ ions dissociating in flight

ORAL

Abstract

Fragmentation of $\textrm{CO}_2$ molecular ions is a commonly studied process. We examine unimolecular dissociation in flight of metastable $\textrm{CO}_2^{2+}$ ions employing the cold target recoil ion momentum spectroscopy (COLTRIMS) technique. The metastable states responsible for dissociation in flight are populated by ultrashort laser pulses. Data analysis is conducted using a previously described method [1]. Analysis of the high statistics delayed $\textrm{CO}_2^{2+} \rightarrow \textrm{CO}^+ + \textrm{O}^+$ channel allows us to further demonstrate the power of our method, in particular the direct determination of the lifetime(s) of the decaying state(s) without the need for simulations typically required by other methods. We also extract the 3-D momentum distributions of the dissociating fragments. We compare our findings to existing results. \\ {[1]} Bethany Jochim et al., New J. Phys. \textbf{19}, 103006 (2017).
