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