The hard core Yukawa potential has two forms, the attractive Yukawa potential:

and the repulsive form

where is the intermolecular pair potential, is the distance, is the hard diameter, is the energy well depth (), and is a parameter that controls the interaction range ().

The repulsive form has been used to study charge-stabilised colloid-colloid interactions.

Critical point

The repulsive form of the potential has no critical point.
