摘要

In this work, we have thoroughly investigated the bulk properties such as binding energy, neutron separation energy, nuclear radii and deformation parameter etc., along with the decay half-lives of various decay modes such as alpha decay and cluster decay of even-even 238−338Rf isotopes. For that we have calculated the decay Q values using the calculated binding energy values which have been accessed by using two force parameters NL3* and NLSH in Relativistic Mean Field (RMF) Model. For the calculation of decay half-lives we have used Viola Seaberg, M. Royer, the Universal Decay Laws-1 and 2, Santhosh's semi-empirical formula, and the Unified formulae. From our investigation, we found possible shell or sub-shell closures at N = 136, 154/156, 162, 178, 184, 192, 218, 220, 222. With a comparison to alpha decay, we found the likelihood of occurrence of cluster radioactivity is significantly lower. The present analysis is informative for the near future experimental synthesis.
