[Introduction] A recent high-resolution
α
,
X
-ray, and
γ
-ray coincidence-spectroscopy experiment offered the first glimpse of
excitation schemes of isotopes along
α
-decay chains of
Z
=
115. To understand these observations and to make
predictions about shell structure of superheavy nuclei below
288
115, we employ two complementary mean-field
models: the self-consistent Skyrme energy density functional approach and the macroscopic-microscopic Nilsson
model. We discuss the spectroscopic information carried by the new data. In particular, candidates for the
experimentally observed
E
1 transitions in
276
Mt are proposed. We find that the presence and nature of low-energy
E
1 transitions in well-deformed nuclei around
Z

,N
=
168 strongly depends on the strength of the
spin-orbit coupling; hence, it provides an excellent constraint on theoretical models of superheavy nuclei. To
clarify competing theoretical scenarios, an experimental search for
E

systems

Mt,
275
Hs, and
277

Khuyagbaatar, J.; Yakushev, A.; Düllmann, Ch.E.; Ackermann, D.; Andersson, L.-L.; Block, M.; Brand, H.; Even, J.; Forsberg, U.; Hartmann, W.; Herzberg, R.-D.; Heßberger, F.P.; Hoffmann, J.; Hübner, A.; Jäger, E.; Jeppsson, J.; Kindler, B.; Kratz, J.V.; Krier, J.; Kurz, N.; Lommel, B.; Maiti, M.; Minami, S.; Rudolph, D.; Runke, J.; Sarmiento, L.G.; Schädel, M.; Schausten, B.; Steiner, J.; De Heidenreich, T. Torres; Uusitalo, Juha; Wiehl, N.; Yakusheva, V. (EDP Sciences, 2016)The fission process still remains a main factor that determines the stability of the atomic nucleus of heaviest elements. Fission half-lives vary over a wide range, 10−19−1024 s. Present experimental techniques for ... -
Stability and synthesis of superheavy elements: Fighting the battle against fission – example of 254No
Lopez-Martens, A.; Henning, G.; Khoo, T.L.; Seweryniak, D.; Alcorta, M.; Asai, M.; Back, B.B.; Bertone, P.; Boilley, D.; Carpenter, M.P.; Chiara, C.J.; Chowdhury, P.; Gall, B.; Greenlees, Paul; Gurdal, G.; Hauschild, K.; Heinz, A.; Hoffman, C.R.; Janssens, R.V.F.; Karpov, A.V.; Kay, B.P.; Kondev, F.G.; Lakshmi, S.; Lauristen, T.; Lister, C.J.; McCutchan, E.A.; Nair, C.; Piot, J.; Potterveld, D.; Reiter, P.; Rowley, N.; Rogers, A.M.; Zhu, S. (EDP Sciences, 2016)Superheavy nuclei exist solely due to quantum shell effects, which create a pocket in the potential-energy surface of the nucleus, thus providing a barrier against spontaneous fission. Determining the height of the ... -
