hmax0 and are obtained from the data in Figure 2. hmax is the average of hmax taken over the 10% smallest bubbles. is the average taken over the 10% largest bubbles. The values inside the brackets are the standard deviation associated with the respective averages. ⟨Δz⟩ is the average z-motion amplitude obtained from the MD simulations, for the smallest bubbles (radius of ∼6 Å for He and Ne and ∼9 Å for Ar). γ is calculated using eq 1 with given by . 2rvdW is the vdW diameter (from ref (21)), and β is the atomic compressibility (from ref (22)).
