- Study of Alpha Decay Chains of Superheavy Nuclei and Magic Number Beyond Z = 82 and N = 126 Shagun Thakur Sushil Kumar Rajesh Kumar Física, Astronomía y Matemáticas SHE Half life Cluster decay We study various α-decay chains on the basis of the preformed cluster decay model. Our work targets the superheavy elements, which are expected to show extra stability at shell closure. Our computations identify the following combinations of proton and neutron numbers as the most stable nuclei: Z = 112, N = 161, 163; Z = 114, N = 171, 178, 179; and Z = 124, N = 194.We also investigate the alternative of heavy cluster emissions in the decay chain of 301120, instead of α decay. Our study of cluster radioactivity shows that the half-life for 10Be decay in 289114 is larger, indicating enhanced stability at Z = 114, N = 175. Similar calculations concerning the emission of 14C and 34Si from 301120 find the more stable combinations Z = 114, N = 173, and Z = 106, N = 161, respectively. From the same parent, 301120, the emission of a 49−51Ca cluster yielding a Z = 100, N = 152 daughter is the most probable. 2013 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46426434005 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3 Vol.43
