Abstract

We have studied the vibrationally relaxed C₂H ion in the heavy – ion storage ring CRYRING in Stockholm. We measured the dissociative recombination absolute cross section over center-of-mass energies in the range between 0 and 0.1 eV by scanning the electron energy.
The rate of different neutral product channels of dissociative recombination was measured. We found the three-body channel C₂H + H + H, with a branching ratio of 59%, to be the dominant one. Finally, we compare C₂H and C₂H ([CITE]) results.
