30 This directory contains a model consisting of the superposition of two shifted
31 Morse pair potentials with different cutoffs.
33 phi_i(r) = epsilon_i * ( - exp[ -2*C_i*(r - Rzero_i) ]
34 + 2*exp[ -C_i*(r - Rzero_i) ] )
37 for i=1,2 and where shift_i is computed so that phi_i(rcut_i) = 0.0. The model
38 uses two neighbor lists with different cutoffs and does not request neighbors
39 of non-contributing particles.
