-# 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
-
-# The following GaN potential is from J. Nord, K. Albe, P. Erhart
-# and K. Nordlund, J. Phys.: Condens. Matter, 15, 5649(2003).
