Generalized exponential model
The Generalized exponential model (or GEM-m potential) is given by (Eq. x in [1]):
- Failed to parse (Conversion error. Server ("https://wikimedia.org/api/rest_") reported: "Cannot get mml. Server problem."): {\displaystyle \Phi _{12}(r)=\epsilon \exp \left[-\left({\frac {r}{\sigma }}\right)^{m}\right]}
