Nuclear structure and decay properties of even-even nuclei in Z = 70-80 drip-line region
Abstract
We study nuclear structure properties for various isotopes of Ytterbium (Yb), Hafnium(Hf), Tungsten(W), Osmium(Os), Platinum(Pt) and Mercury(Hg) in Z = 70-80 drip-line region starting from N = 80 to N = 170 within the formalism of relativistic mean field (RMF) theory. The pairing correlation is taken care by using BCS approach. We compared our results with finite range droplet model(FRDM) and experimental data and found that the calculated results are in good agreement. Neutron shell closure is obtained at N = 82 and 126 in this region. We have also studied probable decay mechanisms of these elements.
