Initial analysis of diffusion timescales. Top: diffusion timescale as a function of the dust temperature (T_d) for θ = 0.65 Bottom: as a function of the surface coverage of CO (θ) at 12 K for the main radicals considered (Furuya et al. 2022). The dotted black line and the shaded region around it show the H accretion timescale for different $n_{H_{atom}}$ $\[n_{\mathrm{H}_{\text {atom }}}\]$ (see Sec. 3.1).
