Short-range repulsive three-body force and the point proton density of3He

We consider anad hoc short-range repulsive three-body force of the form of exp [- (x2 + y2 + z2)/r02], wherex, y andz are interparticle distances andr0 ≲ 1 fm, and examine its effect on the point proton density of3He around the centre. We conclude that, no matter how strong the additional three-body force is, its effect on the, density is insignificant.
