# 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:
#
# Stillinger and Weber,  Phys. Rev. B, v. 31, p. 5262, (1985)
