Square well model: Difference between revisions

Revision as of 14:55, 21 June 2007

The Square well model is given by

Φ (r) = {\begin{matrix} \infty & ; & r < σ \\ - ϵ & ; & σ \leq r < λ σ \\ 0 & ; & r \geq λ σ \end{matrix}

where $Φ (r)$ is the intermolecular pair potential, r is the distance, σ is the hard diameter and λ > 1.
