			# 2-Body n, beta, lambda2, B, lambda1, and A
			# 3-Body lambda3, c, d, and costheta0
			# I think 'R' is dependent on the type of cluster
			# Rutuparna Narulkar @ Oklahoma State University

			# 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,
			# lambda3, c, d, costheta0, n,
			# beta, lambda2, B, R, D, lambda1, A, Chi
