Landscape appreciation of systematic structure properties in even-even nuclei along the valley of stability

Probes of axial and nonaxial hexadecapole deformation effects in nuclei around 230U

“…the vibrating coupling) may to some extent be responsible for the underestimations of β 2 values (the data extracted from BE(2) automatically include the vibrating effect, e.g. see [58] and references therein), especially in the soft nuclei.…”

“…The pairing correlation is defined as the difference between paired solution E LN and no-pairing solution E LN (Δ = 0). As mentioned in [58], after performing the several standard steps, the total energy can be obtained at each sampling deformation grid. Further, the smooth potential-energy surface/map is able to be given with the help of the interpolation techniques, e.g.…”

Discovery of new characterizations of parameter distributions in a semi- empirical mass model: an investigation by dividing an overdetermined system into numerous balanced subsystems*

“…For a nucleus, the equilibrium shape in the ground state is indicated by , which can be obtained by a standard potential-energy-surface calculation (e.g., see Refs. [22][23][24][25] and references therein). The deformation correction energy is calculated using [26,27]…”

Revisiting the island of hexadecapole-deformation nuclei in the A ≈ 150 mass region: focusing on the model application to nuclear shapes and masses

“…Following such an investigation, we further studied the effects of hexadecapole deformations on the shapes of atomic nuclei around 230 U [27]-one of the prominent β 4 regions. In another recent project [32], we refitted a set of macroscopic model parameters which can improve the description of nuclear binding energies. Keeping the above facts in mind, we revisit the island of hexadecapole-deformation nuclei in the A ≈ 150 mass region of the nuclear landscape and perform an extended investigation using MM calculations, primarily paying attention to the effects of hexadecapole-deformation components on nuclear shapes and masses (nuclear binding energies).…”

“…Moreover, the MM models never stop developing, including the microscopic and macroscopic parts, e.g. cf [25,[32][33][34][35]. Part of the aims in this work are listed below: (1) to reproduce nuclear quadrupole deformations with two sets of Woods-Saxon (WS) parameters, and provide a comparison with experimental data and other theoretical results; (2) to improve the description of nuclear masses, by comparing with the results with and without consideration of the hexadecapole deformation; (3) to test the WS parameter sets and the present MM method to some extent.…”
