I was being a little loose with my terminology. By "radius" I meant
"Rmin/2". If you look at the definition of Rmin, it is the distance
between the centers of two atoms when their LJ potential is at a minimum.
For two atoms of the same type, this is double their "radius". Ergo,
radius = Rmin/2. So yes, you're correct.
Sorry for the ambiguity.
All the best,
Jason
