Studies on the Existence of Various 1p, 2p Halo Isotopes via Cluster Decay of Nuclei in Superheavy Region

Study on the decay of Z = 127 – 132 superheavy nuclei via emission of 1-n and 2-n halo nuclei

“…The model can accurately predict the alpha decay chains, heavy particle decays from elements in heavy and superheavy regions; and the predictions are in good agreement with other models such as the universal (UNIV) curve of Poenaru et al [59], universal decay law, the analytical formula of Royer [60], Viola -Seaborg -Sobiczewski semiempirical relation [61], Gamow-like model of Zdeb et al [62] and semiempirical relation of Hatsukawa et al [63]. We would like to point out that we have already used the CPPM for studying the emission of 1-p and 2-halo nuclei [46,47] and to study the emission of various exotic nuclei from superheavy elements [64,65].…”

“…It is to be mentioned that most of the parent nuclei are stable against the decay of 1-n and 2-n halo nuclei; however, we could find some decays that are possible with a decay half-life well within the experimental limit. Such results are given in Table . For other 1-n halo nuclei, 14 B, 17,19 C, 22 N, 26 F, 29,31 Ne, 34,37 Na, 35,37 Mg, and 55 Ca and 2-n halo nuclei 6,8 He, 11 Li, 12,14 Be, 17,19 B, 22 C, 27,29 F, 34 Ne, 36 Na, and 46 P, the half-life of decays are very much above the experimental limit. We have calculated the half-life of decay of the halo nuclei by considering them as a normal spherical cluster and as a deformed nucleus with a rms radius.…”

“…The possible 1-n halo candidates in the selected range are 11 Be, 14 B, 15,17,19 C, 22 N, 23 O, 24,26 F, 29,31 Ne, 34,37 Na, 35,37 Mg, and 55 Ca. The 2-n halo candidates are 6,8 He, 11 Li, 12,14 Be, 17,19 B, 22 C, 27,29 F, 34 Ne, 36 Na, and 46 P. In the present work, we have studied the possibility of the emission of these halo nuclei from elements with Z = 127 -132.…”

“…Our study is motivated by the synthesis of superheavy elements by fusion reactions and the prediction of the existence of elements with higher atomic numbers such as 124, 126, and 128 [43 -45]. We would like to point out that we have already made an attempt to study the formation of proton halo nuclei from superheavy elements and the results were published [46,47].…”
