摘要
We have studied the vibrationally relaxed C2H3+ 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 C2H3+ and C2H2+ (Derkatch et al. 1999) results.
