Generalized exponential model

The Generalized exponential model (or GEM-m potential) is given by (Eq. x in ):

$\Phi _{12}(r)=\epsilon \exp \left[-\left({\frac {r}{\sigma }}\right)^{m}\right]$

where

• $r:=|\mathbf {r} _{1}-\mathbf {r} _{2}|$
• $\Phi _{12}(r)$ is the intermolecular pair potential between two particles or sites

m=1

Also known as the EXP model
