    "abstract": "It is generally believed that quarks being confined inside nucleons should\nmake their presence felt explictly in nuclei only at higher energies. However\nit is shown here that the hole in the centre of $ ^{3}H $, $ ^{3}He $ and $\n^{4}He $, the neutron halos in nuclei, the $ \\alpha - $ and other clustering\neffects in nuclei and the nuclear molecules all basically arise due to the same\nunderlying quark effects. Also the role of triton clustering in very neutron\nrich nuclei is emphasized. These require the concept of hidden colour states\nwhich arise from the confinement ideas of QCD for the multi-quark systems.",
