Figure 2. The minimum potential energy, tm, of a helium atom interacting with the 100 face of an argon crystal is plotted as a function of the position of the helium atom relative to the surface lattice...

There have been many efforts for combining the atomistic and continuum levels, as mentioned in Sect. 1. Recently, Santos et al. [11] proposed an atomistic-continuum model. In this model, the three-dimensional system is composed of a matrix, described as a continuum and an inclusion, embedded in the continuum, where the inclusion is described by an atomistic model. The model is validated for homogeneous materials (an fee argon crystal and an amorphous polymer). Yang et al. [96] have applied the atomistic-continuum model to the plastic deformation of Bisphenol-A polycarbonate where an inclusion deforms plastically in an elastic medium under uniaxial extension and pure shear. Here the atomistic-continuum model is validated for a heterogeneous material and elastic constant of semi crystalline poly( trimethylene terephthalate) (PTT) is predicted. 

Argon crystallizes at —235°C in a face-centered cubic unit cell with a = 5.43 A. Determine the apparent radius of an argon atom in the solid. 

Argon crystallizes in the face-centered cubic arrangement at 40 K. Given that the atomic radius of argon is 191 pm, calculate the density of solid argon. 

The availability of the new three-body nonadditive potential made it possible to investigate the structure of the argon crystal at a much increased level of accuracy compared to that possible earlier and resolve an outstanding problem, often called the rare-gas crystal structure paradox . The cohesion energy of the argon crystal computed...

So far, there seems to be no experimental evidence for the existence of NeN. Neon crystals doped with nitrogen only showed emission lines of nitrogen in the luminescence spectrum in contrast to nitrogen-doped argon crystals where emission from an ArN exciplex was observed [3].
