Figure 2.

Probability density of $U_{v\overline{v}}$ at the γ = 0 state and the γ = 1 state for the homogeneous liquid. The probability density of $U_{v\overline{v}}$ at the γ = 0 state spreads over a much boarder region than at the γ = 1 state. Note that $U_{v\overline{v}}$ at the γ = 0 state has a long decreasing tail. The last bin on the right side of the figure (b) includes all the observations whose $U_{v\overline{v}}$ is larger than 3000 kcal/mol. The total probability in the last bin is 52.0%. The insert shows the overlap of the probability density of $U_{v\overline{v}}$ at the γ = 0 and the γ = 1 states.
