A single sentence description.
Morse pair potential with sigmoidal smoothing at cutoff v001
Description This Model Driver implements a logistic function as the cutoff for the Morse pair potential. It takes five parameters: (1) the cutoff separation in angstroms, (2) the logistic Width, (3) the epsilon parameter in eV, (4) the C parameter in inverse angstroms, and (5) the equilibrium pair separation 'Rzero' in angstroms.
