RCUT
Type: real
Default: [angstrom]
Usage: RCUT {real}
Description: Defines the cutoff parameter of the tersoff potential. This parameter is in principle already defined by the values of bigD and bigR. But it is necessary to define it when using the tersoff in conjunction with other potentials (for the same atomic pair) in order to have the same consistent definition of RCUT for all potentials.
