The Mayer f-function, or f-bond is defined as (Ref. 1 Chapter 13 Eq. 13.2):

where

In other words, the Mayer function is the Boltzmann factor of the interaction potential, minus one.

Diagrammatically the Mayer f-function is written as

Hard sphere model[edit]

For the hard sphere model the Mayer f-function becomes:

where is the hard sphere diameter.
