Martynov Sarkisov Vompe

The Martynov-Sarkisov-Vompe (MSV) (Eq. 33 of ) closure relation is given in terms of the bridge function:

$B^{(2)}(r)=-{\frac {1}{2}}(\omega -\phi )^{2}$

where

$\left.\phi \right.=\rho \epsilon \beta$

where $\phi$ is short-ranged. The Weeks-Chandler-Andersen division of the Lennard-Jones potential was used. (Notice that the Martynov-Sarkisov-Vompe closure, for a hard sphere fluid, becomes the Martynov Sarkisov closure).
