The rotational band structure of the Z ¼ 104 nucleus 256Rf has been observed up to a tentative spin of
20@ using state-of-the-art -ray spectroscopic techniques. This represents the first such measurement in a
superheavy nucleus whose stability is entirely derived from the shell-correction energy. The observed
rotational properties are compared to those of neighboring nuclei and it is shown that the kinematic and
dynamic moments of inertia are sensitive to the underlying single-particle shell structure and the specific
location of high-j orbitals. The moments of inertia therefore provide a sensitive test of shell structure and
pairing in superheavy nuclei which is essential to ensure the validity of contemporary nuclear models in
this mass region. The data obtained show that there is no deformed shell gap at Z ¼ 104, which is
predicted in a number of current self-consistent mean-field models.

Impact of the surface energy coefficient on the deformation properties of atomic nuclei as predicted by Skyrme energy density functionals
Ryssens, W.; Bender, M.; Bennaceur, Karim; Heenen, P.-H.; Meyer, J. (American Physical Society, 2019)Background: In the framework of nuclear energy density functional (EDF) methods, many nuclear phenomena are related to the deformation of intrinsic states. Their accurate modeling relies on the correct description of the ... -
Properties of nuclei in the nobelium region studied within the covariant, Skyrme, and Gogny energy density functionals
Dobaczewski, Jacek; Afanasjev, A. V.; Bender, M.; Robledo, L. M.; Shi, Yue (Elsevier BV, 2015)We calculate properties of the ground and excited states of nuclei in the nobelium region for proton and neutron numbers of 92≤Z≤104 and 144≤N≤156, respectively. We use three different energy-density-functional (EDF) ... -
Theoretical predictions of wimp-nucleus and neutrino-nucleus scattering in context of dark matter direct detection
Pirinen, Pekka (University of Jyväskylä, 2018)The nature of dark matter is at present an open question. Assuming the main component of dark matter consists of weakly interacting massive particles (WIMPs), directly detecting such particle via a scattering process ... -
Muon-electron lepton-flavor-violating transitions : Shell-model calculations of transitions in 27Al
Kostensalo, Joel; Suhonen, Jouni; Civitarese, O. (American Physical Society, 2018)In this paper we present the results of large-scale shell-model calculations of muon-to-electron lepton-flavorviolating transitions for the case of the target nucleus 27Al. We extend the previous shell-model calculations, done ... -

(American Physical Society, 2024)We investigated decays of 51,52,53K at the ISOLDE Decay Station at CERN in order to understand the mechanism of the 𝛽-delayed neutron-emission (𝛽𝑛) process. The experiment quantified neutron and 𝛾-ray emission paths ...
