# 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:
