Feasibility of observing the α decay chains from isotopes of SHN with Z = 128, Z = 126, Z = 124 and Z = 122

Abstract

Taking the Coulomb and proximity potential model for deformed nuclei (CPPMDN) as the interacting potential for the post-scission region, the alpha decay properties of 34 isotopes of the superheavy nuclei with Z = 128 within the range 306 $\le$ A $\le$ 339 have been studied, considering both the parent and daughter nuclei to be deformed. The manuscript also deals with the decay properties of the isotopes of Z = 126 (within 288 $\le$ A $\le$ 339), Z = 124 (within 284 $\le$A $\le$ 339) and Z = 122 (within 280 $\le$ A $\le$ 339). The alpha decay half lives thus evaluated has been compared with the values evaluated using other theoretical models and it was seen that, our theoretical alpha decay half lives matches well with these values. Through the present study, we have underlined and have established the fact that, among the 192 isotopes considered in the present study, only those isotopes ${}^{321-324,328-335}$128, ${}^{318-320,323-327}$126, ${}^{305-308,315-322}$124 and ${}^{298-307,311-314}$122 can be synthesized and detected through alpha decay in laboratory. As the alpha decay half lives of these superheavy isotopes lie within the experimental limits, we hope these predictions, on the decay modes of these unknown nuclei, to pave the way for the future experiments. The proton separation energy calculations on ${}^{306-339}$128, ${}^{288-336}$126, ${}^{284-339}$124 and ${}^{280-339}$122 superheavy nuclei have also been done and the study revealed the probable proton emitters among these nuclei.
