			# 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)
