The experimental and MD determinations of lnΛ versus g. Despite large variation in trap parameters the observed values fall along the same curve, indicating a universal form for lnΛ. The dashed black curve represents the analytical form used here and in [29] (modified to agree with low temperature data), while the other curves represent previous forms described elsewhere [27]. The top x-axis denotes the domain of this graph in terms of the plasma coupling parameter, Γ, which is the ratio of potential to kinetic energy
