Further evidence for a cold solar nebula comes from the observed noble gas enrichment in Jupiter’s atmosphere—trapping argon in icy planetesimals requires temperatures of 30 K (Owen et al. 1999).

However, the recent progress in interpreting the multiphonon HAS from monolayers of noble gas atoms (Ar, Kr, Xe) adsorbed on metals [7–10] makes it now possible to exactly calculate Nki ,Ts (ε, ∆K) and thereby assess the total energy transfer in the studied collisions.
Recovery temperature for nonclassical energy transfer in atom-surface scattering
As a consequence, at the bonding geometry of adsorbed noble-gas atoms which are regarded as exhibiting a van der Waals like bonding, and even more so at the turning point of noble-gas atom scattering at surfaces, the physics is largely determined by the interaction of orbitals and static polarization.
Theory of Adsorption on Metal Substrates
For example, a recent experiment using a two-species noble-gas maser is consistent with there being no Lorentz or CPT violation in the neutron sector at a level of 10−31 GeV .

By analogy to the very successful atomic shell model these magic numbers were taken as evidence of closed shell configurations in atomic nuclei, similar to the noble gas configurations in the electron shells of atoms.

It is also possible that another phase remained in the diamond separate after chemical and physical isolation. Detailed studies show that at least two clearly resolved noble gas components, called “P3” and “HL”, reside in meteoritic nanodiamonds (Fig. 16).
