if your mind wants to be challenged i suggest you to read the nucleus point of view by an LF's great member.
Halo nuclei from one side offer a way to verify nuclear models e.g. those used by LENR society - bringing crucial experimental evidence which has to be included while proposing such models, and suggestions how to build them - e.g. to accept crucial 1D topological vortices in nuclear physics, or requiring to propose an alternative explanation (I still haven't seen any).
From the other side, these are intermediate states between free and fused nucleons - could be intermediate states for fusion ...
And generally their binding, looking necessary 1D structures seems exactly what is needed for fusion - mechanism holding in close distance, also overcoming Coulomb repulsion.
