“…As a consequence of the subtle interplay between single-particle and collective degrees of freedom, nuclei in this region of the nuclear chart display a large variety of intriguing phenomena. Several experimental [2][3][4][5][6][7][8] and theoretical [9][10][11][12][13][14][15][16][17] studies have already been reported on the structure of those nuclei. In particular, the rapid structural change around the neutron number N = 60 has been carefully studied in Zr and Sr isotopes [2,7,12,14,15,[18][19][20].…”

“…On the other hand, the EDF scheme [22][23][24] yields a global description of nuclear matter and bulk nuclear properties. Within this context, the evolution of the nuclear shapes around A = 100 has been studied using self-consistent mean-field (SCMF) approximations based on different parametrizations of the Skyrme [25] and Gogny [7,12] as well as relativistic [14,15,26] EDFs. However, in order to access the excitation spectra and transition rates within the EDF scheme, one needs to go beyond the mean-field level to include dynamical correlations associated with the restoration of the broken symmetries and/or the fluctuations in the collective coordinates.…”

Structural evolution inA≈100nuclei within the mapped interacting boson model based on the Gogny energy density functional

The structure of even-even neutron-rich Ru, Mo, Zr and Sr nuclei in the A ≈ 100 mass region is studied within the interacting boson model (IBM) with microscopic input from the self-consistent mean-field approximation based on the Gogny-D1M energy density functional. The deformation energy surface in the quadrupole deformation space (β, γ), computed within the constrained HartreeFock-Bogoliubov framework, is mapped onto the expectation value of the appropriately chosen IBM Hamiltonian with configuration mixing in the boson condensate state. The mapped IBM Hamiltonian is used to study the spectroscopic properties of 98−114 Ru, 96−112 Mo, 94−110 Zr and 92−108 Sr. Several cases of γ-soft behavior are predicted in Ru and Mo nuclei while a pronounced coexistence between strongly-prolate and weakly-oblate deformed shapes is found for Zr and Sr nuclei. The method describes well the evolution of experimental yrast and non-yrast states as well as selected B(E2) transition probabilities.

Shape coexistence and mixing of low-lying 0+ states in 96Sr

The low energy excited 0 + 2,3 states in 96 Sr are amongst the most prominent examples of shape coexistence across the nuclear landscape. In this work, the neutron [2s 1/2 ] 2 content of the 0 + 1,2,3 states in 96 Sr was determined by means of the d( 95 Sr,p) transfer reaction at the TRIUMF-ISAC2 facility using the SHARC and TIGRESS arrays. Spectroscopic factors of 0.19(3) and 0.22 (3) were extracted for the 96 Sr ground and 1229 keV 0 + states, respectively, by fitting the experimental angular distributions to DWBA reaction model calculations. A detailed analysis of the γ-decay of the isomeric 0 + 3 state was used to determine a spectroscopic factor of 0.33(13). The experimental results are compared to shell model calculations, which predict negligible spectroscopic strength for the excited 0 + states in 96 Sr. The strengths of the excited 0 + 2,3 states were also analyzed within a two-level mixing model and are consistent with a mixing strength of a 2 =0.40(14) and a difference in intrinsic deformations of |∆β| = 0.31(3). These results suggest coexistence of three different configurations in 96 Sr and strong shape mixing of the two excited 0 + states.
