			# DATE: 2011-05-03 CONTRIBUTOR: Aidan Thompson, athomps@sandia.gov CITATION: Tersoff, Phys Rev B, 39, 5566 (1989)

			# Si and C mixture, parameterized for Tersoff potential
			# this file is from Saurav Goel - sg258@hw.ac.uk
			# J. Tersoff, PRB, 39, 5566 (1989) + errata (PRB 41, 3248)

			# Tersoff 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:
			# A,B = eV; lambda1,lambda2,lambda3 = 1/Angstroms; R,D = Angstroms
			# other quantities are unitless

			# format of a single entry (one or more lines):
			# element 1, element 2, element 3,
			# m, gamma, lambda3, c, d, costheta0, n,
			# beta, lambda2, B, R, D, lambda1, A

			# Tersoff's nomenclature - - - c d h n beta mu B R = (R+S)/2 D = (S-R)/2 Lambda A
