    "abstract": "It is now known that in neutron rich nuclei, old magic numbers disappear and\nnew ones appear. Single nucleon and double nucleon separation energies are\nplotted here in all possible manner.Using this data it is shown here for the\nfirst time that nuclei with pair of proton number Z and neutron number N (Z,N)\n: (6,12), (8,16), (10,20), (11,22) and (12,24) exhibit exceptional stability or\nmagicity. As such these magic numbers appear in pairs. This correlation is\nshown here to be indicative of predominance of tritons in the ground state of\nthese neutron rich nuclei. Thus ${^{30}_{10} Ne_{20}}$ has the structure of 10\n$^{3}_{1} H_{2}$ in the ground state. This confirms the prediction of the\nauthor that triton clustering in neutron rich nuclei as a new phenomenon.",
