Models[edit]
Buckingham potential[edit]
The Buckingham potential for neon is given by (Eq. 26 [1]):
where is in ergs ( 10−7 J) and in Å.
HBV potential[edit]
The Hellmann-Bich-Vogel potential [2].
Lennard-Jones parameters[edit]
Some Lennard-Jones parameters for neon are listed in the following table:
| Authors | (meV) | (nm) | Reference |
| Herrero | 3.0840 | 0.2782 | [3] |
| Ramírez and Herrero | 3.2135 | 0.2782 | [4] |
Leonhard and Deiters potential[edit]
[5].
NE2 potential[edit]
[6].
Phase diagram[edit]
The phase diagram for temperatures in the range of 17–50 K and pressures between 10−2 and 2×103 bar has been calculated in Ref. 2. The critical point was located at and bar (Ref. 2 Table I), and the triple point at and bar (Ref. 2 Table II).
Crystallization line[edit]
The structural regularities along the crystallization line has been studied by way of path integral Monte Carlo simulations and the Ornstein-Zernike pair equation [7].
