The continuous shouldered well model (CSW) is given by ([1] Eq. 1):
![{\displaystyle \Phi _{12}(r)={\frac {U_{R}}{1+\exp[\Delta (r-R_{R})/a]}}-U_{A}\exp \left[-{\frac {(r-R_{A})^{2}}{2\delta _{A}^{2}}}\right]+\left({\frac {a}{r}}\right)^{24}}](https://wikimedia.org/api/rest_v1/media/math/render/svg/bbc66fc37940b5e744613ca304f08b86ec9574a5)
where is the intermolecular pair potential, is the energy of the repulsive shoulder, is the energy of the attractive well, is the diameter of the particles, and Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle r := |\mathbf{r}_1 - \mathbf{r}_2|} .
