Halo structure in neutron rich nuclei with Z<=20  is identified by calculating the neutron separation energies and on the basis of potential energy considerations. The 1n + core configuration of proposed 1-neutron halo nuclei between z=10  and Z=20 is found shifted to 2n + core configuration in higher angular momentum states. The calculation of half-life of decay is performed by considering the proposed halo nuclei as spherical cluster and as deformed nuclei with a rms radius. Except for <sup>15</sup>C, the half-life of decay is found decreased when the rms radius is considered. Only the 1-neutron halo nuclei <sup>26</sup>F and <sup>55</sup>Ca showed half-lives of decay which are less than the experimental limit. None of the proposed 2-neutron halo nuclei have shown a half-life of decay lower than the experimental limit. Also, the probability for the emission of neutron halo nuclei is found to be less in super-heavy region when compared with the clusters of same isotope family. Further, neutron shell closure at neutron numbers 150, 164 and 184 is identified form the plot of  log<sub>10</sub> T<sub>1/2</sub> verses the neutron number of parents. The plots of Q<sup>-1/2</sup> verses log<sub>10</sub> T<sub>1/2</sub> and -ln P verses log<sub>10</sub> T<sub>1/2</sub> for various halo nuclei emitted from the super-heavy elements are found to be linear showing that Geiger-Nuttall law is applicable to the emission of neutron halo also.</p>}, number={1}, journal={Journal of Nuclear Physics, Material Sciences, Radiation and Applications}, author={Biju, R.
