Re: [lammps-users] A question about the "1/2 parameter before φ_αβ" in the EAM function in LAMMPS

I am not omniscient. You have to either ask the author of “the paper” or just test empirically with which setting you can reproduce the results from the publication you are looking at. Those tests need to be done anyway.

LAMMPS implements the functional form as it is described in the manual which is taken from the references quoted within.
