# 2-Body n, beta, lambda2, B, lambda1, and A
# 3-Boby lambda3, c, d, and costheta0
# I thik 'R' is dependent on the type of cluster

# 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
