[edit] Lennard-Jones parameters
Some Lennard-Jones parameters for neon are listed in the following table:
| Authors | \(\epsilon\) (meV) | \(\sigma\) (nm) | Reference |
| Herrero | 3.0840 | 0.2782 | |
| Ramírez and Herrero | 3.2135 | 0.2782 | |
[edit] Buckingham potential
The Buckingham potential for neon is given by (Eq. 26
[edit] 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 \(T_c =46.7 ~{\mathrm K} \) and \(p_c = 27.7 \) bar (Ref. 2 Table I), and the triple point at \(T_{tp} =24.55 ~{\mathrm K} \) and \(p_{tp} = 0.315 \) bar (Ref. 2 Table II).
