Continuous shouldered well model

The continuous shouldered well model (CSW) is given by (^[1] Eq. 1):

Φ_{12} (r) = \frac{U_{R}}{1 + \exp [Δ (r - R_{R}) / a]} - U_{A} \exp [- \frac{(r - R_{A})^{2}}{2 δ_{A}^{2}}] + {(\frac{a}{r})}^{24}

where $Φ_{12}$ is the intermolecular pair potential, $U_{R}$ is the energy of the repulsive shoulder, $U_{A}$ is the energy of the attractive well, $a$ is the diameter of the particles, and $r : = | r_{1} - r_{2} |$ .
