Notes. The fit parameters α, β, and γ correspond to the modified Arrhenius rate law k = α (T/ 300)β exp(−γ/T). The fit is valid in the temperature range 5–50 K, and for a range of medium densities limited by the critical density (see the main text). Reactions forbidden by spin selection rules and identity reactions were omitted. The notation a(b) denotes a × 10b.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
