spheropack.rejection_free.SoftSpheres(epsilon=1.0, sigma=1.0, alpha=2.0)

Soft repulsion \(\frac{\epsilon}{\alpha}(1 - r/\sigma)^\alpha\) for \(r < \sigma\) (harmonic for \(\alpha = 2\), Hertzian for \(\alpha = 5/2\)).

Parameters:

• epsilon (float)

• sigma (float)

• alpha (float)

Return type:

PairPotential
