内容記述 | One of the most important quantities in the hydrogenation reactions of CO molecules to yield H2CO and CH3OH in the ice is the diffusion constant of hydrogen atoms in the ice. The experimental data of CO depletion measured by Watanabe et al. (2003, ApJ, 588, L121) was analyzed, and obtained the diffusion constant of DH = 1.6 x 10(exp -4) ML(sup 2) s(sup -1) in H2O + CO ice at the temperature of 15 K, where ML stands for monolayers. It is suggested that the dominant mechanism of hydrogen atoms at 15 K is quantum tunneling by estimating the activation energy of diffusion. | |||||
