“…2. The α-decay branch to 280 Ds was established only very recently [12]. We note that the PES of the respective isotones with Z þ 2, i.e., the members of the 294 Og decay chain, look very similar since the dependence of the shape evolution on the atomic number Z is weak (compare Fig.…”

“…3, the energy of the 2 þ 1 state nicely agrees with the theoretical expectation while the 0 þ 2 state is predicted at a slightly higher excitation energy. The α decay to an excited state in 282 Cn was observed in one out of the 29 decays of 286 Fl studied so far [12]. In contrast, no such event was detected yet in the decay of 288 Fl, of which 51 cases were studied.…”

“…The quadrupole deformation for the even-even daughter nuclei in table 1 decreases with increasing their neutron number approaching to the next spherical closed shell at N 0 = 184. The minimum value of I α (2 + /0 + ) obtained in this region is that for 286 Fl [8,10]. Note that two indicated values of E 2+ ( 282 Cn) = 0.22 MeV [10] and 0.07 MeV [3] are considered in calculating the corresponding partial α-decay intensity.…”

“…Thus the low excitation energy of the 1/2 − [521] level could be a hint that the spherical proton shell may rather be located at Z = 120 than at Z = 114. It should be noted in this context that in a recent decay study of 286 Fl [29] the authors came to a similar conclusion, stating that the next proton shell closure beyond 208 Pb (Z = 82) would not be located at Z = 114.…”
