TwoBodyAlpha

class TwoBodyAlpha : public feasst::ModelTwoBody

The two-body alpha model is defined as

\(U = s\epsilon \left(\frac{\sigma}{r}\right)^\alpha\)

where \(s\) is the prefactor and \(\alpha\) is the power, both of which are given as class-specific parameters. Note that \(s\) is required for negative values because \(\epsilon\) cannot be negative due to the standard mixing rules.

Public Functions

TwoBodyAlpha(argtype args = argtype())

args:

• alpha: set the value of \(\alpha\). A comma-separated list provides an alpha for each potential.

• s: set the value of \(s\) with a comma-separated list.

void serialize(std::ostream &ostr) const

Output a serialized version of the existing model.
