Experimental study reveals dissociative recombination rate coefficients for small hydrocarbon ions, indicating rapid chemical destruction pathways in cold interstellar clouds.

Key Points

To measure the electron-ion dissociative recombination cross sections and determine the low-temperature rate coefficients for C2+, C2H+, C2H2+, and C2H3+.
Measured electron-ion dissociative recombination cross sections over an energy range of 0.02 to 1 eV using the merged beam technique.
Derived thermal rate coefficients at 100 K by assuming a Maxwellian distribution of electron velocities.
Derived rate coefficients at 100 K for C2+, C2H+, and C2H2+ are each 1.0 × 10-6 cm-3 s-1.
Derived rate coefficient at 100 K for C2H3+ is 1.6 × 10-6 cm-3 s-1.
