    "abstract": "Recent experiments clearly demonstrate the importance of the excited state\n$2^+$ at 1.8 MeV in the substruture ${^6}He$ for the ground state of the\nnucleus ${^8}He$. It is shown here that this means that the ground state\nstructure of ${^8}He$ rather than being $\\alpha$ + 4n is actually ${^3}H$ +\n${^3}H$ +2n. As such the pair of tritons would form a compact core around which\nthe two valence neutrons provide a halo structure in ${^8}He$. Hence both\n${^6}He$ and ${^8}He$ are two neutron halo nuclei but with cores of quite\ndifferent nature. All this demonstrates significance of triton clustering in\nneutron rich nuclei.",
