Studies on the emission of various exotic fragments from superheavy nuclei via cluster decay process

Structure of various exotic fragments such as 7Be, 10,11C, 13,14,15O, 19Ne, 20,21Na and 22,23Mg are studied by computing the separation energy. It is found that 7Be, 11C, 13,14,15O, 19Ne, 20,21Na and 22,23Mg isotopes have lower S(p) than S(2p) but 10C has lower S(2p) than S(p). The driving potential...

Description
Summary:Structure of various exotic fragments such as 7Be, 10,11C, 13,14,15O, 19Ne, 20,21Na and 22,23Mg are studied by computing the separation energy. It is found that 7Be, 11C, 13,14,15O, 19Ne, 20,21Na and 22,23Mg isotopes have lower S(p) than S(2p) but 10C has lower S(2p) than S(p). The driving potential for the exotic nuclei 7Be, 10,11C, 13,14,15O, 19Ne, 20,21Na and 22,23Mg with different angular momentum (with l=0, 1, 2 and 3) is also studied. The minima in the plot of driving potential is consistent with the results of separation energy computations. We have also analyzed the probability of emission of the above exotic fragments from various isotopes with Z=103 to 118 in the superheavy region using Coulomb and Proximity Potential Model. From the computed half-lives, it is deduced that the emission of 7Be, 10,11C, 14O and 15O exotic clusters from superheavy parent isotopes are the most probable.
