# EDIP 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

# format of a single entry (one or more lines)

#

#   element 1, element 2, element 3, 

#     A   B   cutoffA   cutoffC   alpha   beta   eta 

#     gamma   lambda    mu   rho   sigma   Q0 

#     u1   u2   u3   u4

#

# units for each parameters:

#     A , lambda are in eV  

#     B, cutoffA, cutoffC, gamma, sigma are in Angstrom

#     alpha, beta, eta, mu, rho, Q0, u1-u4 are pure numbers 

# Here are the original parameters in metal units, for Silicon from:

# J. F. Justo, M. Z. Bazant, E. Kaxiras, V. V. Bulatov, S. Yip

#       Phys. Rev. B 58, 2539 (1998)
