Neon (Ne)
Lennard-Jones parameters
Some Lennard-Jones parameters for neon are listed in the following table:
| Authors | (meV) | (nm) | Reference |
| Herrero | 3.0840 | 0.2782 | [1] |
| Ramírez and Herrero | 3.2135 | 0.2782 | [2] |
Phase diagram
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).
