Dependence of Chemical Abundance on the Cosmic Ray Ionization Rate in IC 348

Gan Luo, Zhi-Yu Zhang, Thomas G. Bisbas +8

Ions (e.g., H${}_3^{+}$, H${}_2$O${}^{+}$) have been used extensively to quantify the cosmic-ray ionization rate (CRIR) in diffuse sightlines. However, measurements of CRIR in low-to-interme…
