# B and N mixture, parameterized for ExTeP potential
# ExTeP 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):
#I J K m, gamma*, lambda3, c, d, h, n, gamma, lambda2, B, R, D, lambda1, A
