At present, the research into the synthesis of superheavy elements is being pursued under two main goals. One goal is to synthesize elements with larger atomic numbers, and the other is to reach the Island of Stability predicted as the next doubly magic nucleus. The periodic table is currently extended up to element 118, Oganesson (Og) [1], and experiments aimed at the synthesis of element 119...

Superfluidity can significantly influence the dynamics of fermionic systems. On the one hand, it produces an excitation gap that suppresses dissipative processes and facilitates large-amplitude collective motion. On the other hand, the spontaneous breaking of U(1) symmetry gives rise to additional collective excitations, including Goldstone and Higgs modes.
In nuclear systems, these...

An accurate description of nuclear fission still remains a major challenge in today’s nuclear structure physics. İn this talk, we will discuss recent advances in the microscopic description of spontaneous nuclear fission, including the role of tensor interactions. It will be shown that in the case of super heavy elements, the reduction of the inner barrier heights represents a major...

Heavy-ion fusion-evaporation reactions populating nuclei near Z ≈ 85–90 reveal an evaporation-channel puzzle: charged-particle channels pxn and axn are enhanced relative to pure neutron evaporation (xn). In several cases the axn channel exceeds xn by up to two orders of magnitude. A weaker but structurally analogous enhancement is predicted for selected superheavy-element reactions — including...

In a recent study, we introduced a six-dimensional Langevin-based formalism as a proof of principle for modeling heavy-ion fusion dynamics. This approach, incorporating elongation, neck, and asymmetry variables with fully unrestricted motion, naturally produces overdamped dynamics and rapid neck stabilization. Using a Yukawa-plus-exponential folding potential and Gaussian random forces, we...

We study even-even superheavy nuclei $(104 \leq Z \leq 126,\, N \leq 258)$ using a five-dimensional collective Hamiltonian based on triaxial relativistic Hartree-Bogoliubov calculations with the PC-PK1 functional, explicitly incorporating quantum shape fluctuations (QSFs) beyond the mean-field. The model accurately reproduces binding, separation, and $\alpha$-decay energies. A shape evolution...

In the theoretical description of the nuclear fission, the potential energy surface (PES) plays a vital role in analyzing the process. One crucial region of this process is just before scission, where pre-fragments develop their near-final configuration [1]. It has been demonstrated that employing multiple constraints on collective variables can be beneficial in obtaining a more detailed and...

The fission barrier height serves as a crucial quantity in understanding the stability of superheavy nuclei and estimating the survival probabilities of a compound nucleus in a heavy ion fusion reaction, while its variation across the nuclear chart characterizes the landscape of the ``island of stability'' of superheavy nuclei. In this work, we perform the first systematic microscopic...
