The phrase "atomic sphere" is correct and usable in written English.
It can be used in scientific contexts, particularly in chemistry or physics, to describe a model or concept related to atomic structure.
Example: "In quantum mechanics, the electron cloud can be visualized as an atomic sphere surrounding the nucleus."
Alternatives: "atomic model" or "atomic structure".
The electronic structure and total energy of the C15 intermetallic phase NbCr2 have been calculated using the linear muffin tin orbital (LMTO) method with the atomic sphere approximation (ASA).
We use atomic sphere radii of 1.86, 1.6, and 2.1 bohr for Fe, O, and Ag, respectively.
They must also accept the inference that the mathematical produce heat and combustion, since they too possess angles and contain atomic spheres and pyramids, especially if there are, as they allege, atomic figures.
It is assumed that atomic spheres do not overlap.
The following radii of atomic spheres were used: Al = 2.34 a.u., Fe = 1.87 a.u., and C = 1.66 a.u. Figure 1 shows a unit cell corresponding to the stoichiometric composition of the K-phase (on the left) and slightly modified unit cell (on the right) which was shifted towards the vector (for clarity) and which has a carbon atom in place of octahedral pore.
The radii of the atomic spheres (RMT) for the Li+, La3+, Zr4+, O, and Al3+ ions were chosen to be 1.46, 2.27, 1.93, 1.71, and 1.40 au, respectively.
Three types of chemical restraint were used; hard sphere atomic radii, fixed B−O bond networks, and bond valence restraints.
It is clearly shown that our continuum mechanics-based model, in which an atomistic configuration is represented by a discretised continuum representation of the surface using a hard-sphere atomic model, is capable of reproducing many of the features identified through detailed atomistic simulations.
Here, V int is given by the number of atoms within the sphere (with a fixed radius R) multiplied by the mean atomic volume found in proteins; V ext is the difference between the volume of the sphere and V int, which denotes the remaining volume of the sphere.
With the size of the sphere, its average atomic mass, and its atomic spacing known, the required sphere diameter can be calculated with sufficient precision and low uncertainty to enable it to be finish-polished to a target mass of one kilogram.
Prior to this, as Bohr remarked, spectra seemed as beautiful and meaningless as butterflies' wings, but now, in the words of another great pioneer, Arnold Sommerfeld, they were revealed as "a true atomic music of the spheres".
