			# Si and C mixture, parameterized for Tersoff potential
			# this file is from Rutuparna.Narulkar @ okstate.edu
			# values are from Phys Rev B, 39, 5566-5568 (1989)
			# and 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
