At a 3 body system we first are confronted with a choice, are the three bodies lined up or put in a triangular shape?!

Nature is not LEGO like organized. The SO(4) model clearly shows that in 4-He the flux of all proton joins and hence a new single body comes into existence. The same holds for all nuclei we know. There is some structure as e.g. in 6-Li where the more dense 4-He is orbited by a Deuterium and the resulting binding is weak.

In general we can say that the core of all isotopes is a complex connected alpha -particle "wave". If a model is not able to calculate gamma lines in relation to a claimed bond structure then you can just use it for descriptive tasks.

And last: If a model uses spheres we can directly conclude its Kindergarten and unphysical as spheres are not allowed topologies for stable flux.
