Inelastic H + H${}_3^{+}$ Collision rates and their impact in the determination of the excitation temperature of H${}_3^{+}$

Daniel Felix-Gonzalez, Pablo del Mazo-Sevillano, Alfredo Aguado +5

Context. In dffuse interstellar clouds the excitation temperature derived from the lowest levels of H${}_3^{+}$ is systematically lower than that derived from H2. The differences may b…
