# Stillinger-Weber parameters for various elements and mixtures

# multiple entries can be added to this file, LAMMPS reads the ones it needs

# these entries are in LAMMPS "metal" units:

#   epsilon = eV; sigma = Angstroms

#   other quantities are unitless

# format of a single entry (one or more lines):

#   element 1, element 2, element 3, 

#   epsilon, sigma, a, lambda, gamma, costheta0, A, B, p, q, tol

# Here are the original parameters in metal units, for Silicon from:
