The Lennard-Jones model for argon.

Argon has a mass of 39.948 umas. The Lennard-Jones parameters for liquid argon are \epsilon/k_B \approx 119.8 K and \sigma \approx 0.3405 nm. (Ref. 1). Barker, Fisher and Watts used the values \epsilon/k_B \approx 142.095 K and \sigma \approx 0.33605 nm. (Ref. 2 Table 1).
