The Implications of a High Cosmic-Ray Ionization Rate in Diffuse Interstellar Clouds
Nick Indriolo, Brian D. Fields, Benjamin J. McCall
Diffuse interstellar clouds show large abundances of H_3^+ which can be maintained only by a high ionization rate of H_2. Cosmic rays are the dominant ionization mechanism in this…

H3+ in Diffuse Interstellar Clouds: a Tracer for the Cosmic-Ray Ionization Rate
Nick Indriolo, Thomas R. Geballe, Takeshi Oka +1
Using high resolution infrared spectroscopy we have surveyed twenty sightlines for H3+ absorption. H3+ is detected in eight diffuse cloud sightlines with column densities varying f…
