“…Also, as already mentioned in the Introduction, the interpretation of the available information about rotational bands of neutron-rich Rh isotopes and nuclides in adjacent isotopic chains [15][16][17][84][85][86][87][88] consistently requires the assumption of triaxial shapes within the various approaches used to model them.…”

Precision mass measurements of neutron-rich rhodium isotopes have been performed at the JYFLTRAP Penning trap mass spectrometer at the Ion Guide Isotope Separator On-Line (IGISOL) facility. We report results on ground-and isomeric-state masses in 110,112,114,116,118 Rh and the very first mass measurement of 120 Rh. The isomeric states were separated and measured for the first time using the phase-imaging ion-cyclotron-resonance (PI-ICR) technique. For 112 Rh, we also report new half-lives for both the ground state and the isomer. The results are compared to theoretical predictions using the BSkG1 mass model and discussed in terms of triaxial deformation.

“…IIIC in Ref. [15]) has been shown to be very successfully in both nuclear spectroscopy [68][69][70][71] and binding energy [15] calculations. In particular, it gives a good description of the nuclear momentum of inertia and high spin states.…”

Background:The deviation between different model calculations that may occur when one goes toward regions where the masses are unknown is getting increased attention. This is related to the uncertainties of the different models which may have not been fully understood.Purpose: To explore in detail the effect of the isospin dependence of the spin-orbital force in the Woods-Saxon potential on global binding energy and deformation calculations. Method:The microscopic energies and nuclear deformations of about 1850 even-even nuclei are calculated systematically within the macroscopic-microscopic framework using three Woods-Saxon parameterizations, with different isospin dependences, which were constructed mainly for nuclear spectroscopy calculations. Calculations are performed in the deformation space (β2, γ, β4). Both the monopole and doubly stretched quadrupole interactions are considered for the pairing channel.Results: The ground state deformations obtained by the three calculations are quite similar to each other. Large differences are seen mainly in neutron-rich nuclei and in superheavy nuclei. Systematic calculations on the shapecoexisting second minima are also presented. As for the microscopic energies of the ground states, the results are also very close to each other. Only in a few cases the difference is larger than 2 MeV. The total binding energy is estimated by adding the macroscopic energy provided by the usual liquid drop model with its parameters fitted through the least square root and minimax criteria. Calculations are also compared with the results of other macroscopic-microscopic mass models.Conclusions: All the three calculations give similar values for the deformations, microscopic energies and binding energies of most nuclei. One may expect to have a better understanding of the isospin dependence of the spinorbital force with more data on proton-and neutron-rich nuclei.

“…Considerable progress in the experimental synthesis of heaviest nuclei has been achieved recently by the Flerov Laboratory in Dubna [1,2,3,4,5,6,7,8,9,10,11] and was partially confirmed in the laboratories at GSI [12,13,14,15,16], LBNL [17] and RIKEN [18]. Nonetheless, the fundamental question of what is the largest possible atomic number of an atomic nucleus is still unanswered.…”

Fission barriers and probabilities of spontaneous fission for elements with Z≥ 100

This is a short review of methods and results of calculations of fission barriers and fission halflives of even-even superheavy nuclei. An approvable agreement of the following approaches is shown and discussed: The macroscopic-microscopic approach based on the stratagem of the shell correction to the liquid drop model and a vantage point of microscopic energy density functionals of Skyrme and Gogny type selfconsistently calculated within Hartree-Fock-Bogoliubov method. Mass parameters are calculated in the Hartree-Fock-Bogoliubov cranking approximation. A short part of the paper is devoted to the nuclear fission dynamics. We also discuss the predictive power of Skyrme functionals applied to key properties of the fission path of 266 Hs. It applies the standard techniques of error estimates in the framework of a χ 2 analysis.
