Experimental determination of the dissociative recombination rate coefficient for rotationally-cold CH${}^{+}$ and its implications for the diffuse cloud chemistry

Daniel Paul, Manfred Grieser, Florian Grussie +13

Observations of CH${}^{+}$ are used to trace the physical properties of diffuse clouds, but this requires an accurate understanding of the underlying CH${}^{+}$ chemistry. Until this work,…
