A microscopic theoretical framework based on relativistic energy density functionals (REDFs) is applied to
studies of shape evolution, excitation spectra, and decay properties of transactinide nuclei. Axially symmetric and
triaxial relativistic Hartree-Bogoliubov (RHB) calculations, based on the functional DD-PC1 and with a separable
pairing interaction, are performed for the even-even isotopic chains between Fm and Fl. The occurrence of a
deformed shell gap at neutron number N = 162 and its role on the stability of nuclei in the region around Z = 108
is investigated. A quadrupole collective Hamiltonian, with parameters determined by self-consistent constrained
triaxial RHB calculations, is used to examine low-energy spectra of No, Rf, Sg, Hs, and Ds with neutron number
in the interval 158 N 170. In particular, we analyze the isotopic dependence of several observables that
characterize the transitions between axially symmetric rotors, γ -soft rotors, and spherical vibrators. An interesting
example of a possible occurrence of shape-phase transitions and critical-point phenomena in this mass region is
explored.

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) ... -

Haverinen, Tiia; Kortelainen, Markus; Dobaczewski, J.; Bennaceur, K. (Jagellonian University, 2019)We take an additional step towards the optimization of the novel finite-range pseudopotential at a constrained Hartree–Fock–Bogolyubov level and implement an optimization procedure within an axial code using harmonic ... -
Rotational properties of nuclei around 254 No investigated using a spectroscopic-quality Skyrme energy density functional
Shi, Yue; Dobaczewski, Jacek; Greenlees, Paul (American Physical Society, 2014)Abstract. Background: Nuclei in the Z≈100 mass region represent the heaviest systems where detailed spectroscopic information is experimentally available. Although microscopic-macroscopic and self-consistent models have ... -
Gamow-Teller response in the configuration space of a density-functional-theory–rooted no-core configuration-interaction model
Konieczka, M.; Kortelainen, Markus; Satuła, W. (American Physical Society, 2018)Background: The atomic nucleus is a unique laboratory in which to study fundamental aspects of the electroweak interaction. This includes a question concerning in medium renormalization of the axial-vector current, which ...
