“…This is consistent with the previous results with the non-relativistic Skyrme-Hartree-Fock method [11]. On the other hand, for the Si isotopes, the deformation parameter for the 28,30,32 Si nuclei is drastically changed when a Λ particle is added, although the change for the other Si isotopes is small. That is, the 28,30,32 Si nuclei have oblate shape in the ground state.…”

“…We confirm that our conclusion remains the same for both the treatments of the pairing correlation, due to the fact that N or Z=14 is an oblate magic number [32]. We therefore conclude that the Λ particle significantly changes the deformation of 28 Si nucleus, at least for the two parameter sets of the RMF Lagrangian and irrespective of the treatment of pairing correlations.…”

We study the deformation property of Λ hypernuclei using the relativistic mean field (RMF) method. We find that 29 Λ Si and 13 Λ C hypernuclei have spherical shape as a consequence of the additional Λ particle, whereas the corresponding core nuclei, 28 Si and 12 C, are oblately deformed. Most of other hypernuclei have a similar deformation parameter to the core nucleus, in accordance with the previous study with the non-relativistic Skyrme-Hartree-Fock method. We discuss the sensitivity of our results to the choice of pairing interaction and to the parameter set of the RMF Lagrangian.

“…On the other hand, different calculated Nilsson singleparticle level schemes indicate that such a gap may occur for N = 142 at β 2 values around 0.22 -0.23, in addition to the N = 152 gap occuring at higher values, with β 2 around 0.28 -0.29 [8,16]. In some cases, the subshell gap predicted at N = 142 in nuclei of mass ≈ 240 is explicitely indicated, in addition to that at N = 152 [17][18][19]. The occurence of such a shell gap should result from intricate structure details that dictate the relative positions of the deformed orbitals originating in the spherical shells 1i 11/2 , 1j 15/2 , and 2g 9/2 .…”

The structural evolution of the heavy nuclei, with Z > 82, is investigated by looking at the differential variation of the two-neutron separation energies. It indicates, by non-monotonous behavior at certain neutron numbers, structure phenomena such as major shell (N = 126) and deformed subshell (N = 152) closures. Another interesting effect is observed at N ∼ 142, which is very well correlated with a previously observed, intriguing behavior of quantities measured in alpha decay, such as relative branching ratios and hindrance factors of excited states from the ground state band of deformed nuclei in this region. Corroboration of the existing experimental data indicates another possible deformed subshell closure.

The Cranking Nilsson model is applied to calculate the single-particle energy eigenvalues and eigenfunctions of nuclei in a strongly deformed potential. parameter. Furthermore, the single-particle Schrödinger fluid is applied to calculate the rigid-body model, the cranking-model and the equilibriummodel moments of inertia of the five uranium isotopes. Moreover, the collective model is applied to calculate the rotational energies of these isotopes. The best potential and deformation parameters are also given.
