Comparison of two fit results for different choices of k(T = 10   K). The UDFA rate coefficient, valid between 295 and 8000 K, is shown in light blue. The best fit for k(10   K) = 10-50 is shown as red, dashed line (α = 1.01(− 11) = 0.23 = 913). The best fit for k(10   K) = k(Tmin) is shown as red, solid line (α = 9.95(− 12), β = 1.05, γ = −42.5).
