Lennard-Jones parameters
The Lennard-Jones parameters for neon are listed in the following table:
Authors | (meV) | (nm) | Reference |
Herrero | 3.0840 | 0.2782 | Ref. 2 |
Ramírez and Herrero | 3.2135 | 0.2782 | Ref. 4 |
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. 4. The critical point was located at and bar (Ref. 4 Table I), and the triple point at and bar (Ref. 4 Table II).
