Soft sphere attractive Yukawa model

The Soft sphere attractive Yukawa model is given by (Eq. 1 in ):

$\Phi _{12}\left(r\right)=A\left({\frac {\sigma _{s}}{r}}\right)^{n}-\left({\frac {\epsilon \sigma }{r}}\right)\exp \left[-\kappa \left({\frac {r}{\sigma }}-1\right)\right]$

which is an amalgamation of the soft sphere potential with the attractive hard core Yukawa potential.
