BMHFTD

Section can be repeated.

References: Fumi1964, Tosi1964

This section specifies the input parameters for the BMHFTD potential type. Functional form: V(r) = Aexp(-Br) - f_6*(r)C/r^6 - f_8(r)D/r^8 where f_order(r) = 1 - exp(-BDr)\sum_{k=0}^order (BDr)^k/k! (Tang-Toennies damping function). No pre-defined parameter values are available. [Edit on GitHub]
