Editing Soft-core mean spherical approximation

Junzo Chihara (along with Madden and Rice) extended the [[Percus Yevick]] equation for [[Lennard-Jones]] systems to provide a soft-core [[Mean spherical approximation | mean spherical approximation]],
the SMSA,


:<math>B(r) = \beta \Phi_{12} (r) - \gamma (r) + \ln \left( 1 + \gamma (r) -  \beta \Phi_2 (r)  \right)</math>

where <math>\Phi_{12} (r)</math> is the [[Intermolecular pair potential | pair potential]], <math>\gamma (r)</math> is the [[Indirect correlation function | indirect correlation function]], and <math> \beta = 1(/k_B T) </math>, where <math>k_B</math>
is the [[Boltzmann constant]].
