			# Si and C mixture, parameterized for Tersoff potential
			# this file is from ulomek(at)imm.rwth-aachen.de
			# values are from Erhart/Albe - Phys Rev B, 71, 035211 (2005)

			# m=n=beta=1
			# R,D,gamma,c,d ->same
			# lambda1=betasqrt(2S)
			# lambda2=beta*sqrt(2/S)
			# lambda3=2*mu=0
			# costheta0=-h
			# A=D0/(S-1)exp(lambda1r0)
			# B=SD0/(S-1)exp(lambda2*r0)

			# 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
