“…In what concerns the density probability of the first 0 + excited state, it is consistent with the microscopic findings of Ref. [66] regarding the 70,72 Se isotopes. The two peaks of the 0 + β density probability from Fig.3(b) correspond to the two turning points of the surface oscillation, with a clear preference for the smallest deformation which maintain a harmonic behaviour as in the spherical case.…”

An exact analytical solution for the Bohr Hamiltonian with an energy dependent Coulomb-like γ-unstable potential is presented. Due to the linear energy dependence of the potential's coupling constant, the corresponding spectrum in the asymptotic limit of the slope parameter resembles the spectral structure of the spherical vibrator, however with a different state degeneracy. The parameter free energy spectrum as well as the transition rates for this case are given in closed form and duly compared with those of the harmonic U (5) dynamical symmetry. The model wave functions are found to exhibit properties that can be associated to shape coexistence. A possible experimental realization of the model is found in few medium nuclei with a very low second 0 + state known to exhibit competing prolate, oblate and spherical shapes.

“…Recently the first measurement of low-lying states in the neutron-rich 110 Zr and 112 Mo was performed via in-beam γ-ray spectroscopy. Lowlying 2 + 1 states observed at excitation energies 185 (11) and 235 (7) keV, respectively, as well as R 42 values ∼ 3, indicate that both nuclei are well deformed [48]. The present study has also shown that 110 Zr does not exhibit a stabilizing shell effect corresponding to the harmonic oscillator magic numbers Z = 40 and N = 70, thus pointing to possible shape coexistence in this mass region.…”

“…Because a rigid deformation in the ground state was observed in the heavier 104 Mo and 106 Mo isotopes [62] [63]. Therefore, the properties of the investigated Mo isotopes are influenced by the quadrupole deformation and the triaxial shape.…”

Low-energy tail of the giant dipole resonance inMo98andMo100

Dipole-strength distributions in the nuclides 98 Mo and 100 Mo up to the neutron-separation energies have been studied in photon-scattering experiments at the bremsstrahlung facility of the Forschungszentrum Dresden-Rossendorf. To determine the dipole-strength distributions up to the neutron-emission thresholds, statistical methods were developed for the analysis of the measured spectra. The measured spectra of scattered photons were corrected for detector response and atomic background by simulations using the code GEANT3. Simulations of γ -ray cascades were performed to correct the intensities of the transitions to the ground state for feeding from higher-lying levels and to determine their branching ratios. The photoabsorption cross sections obtained for 98 Mo and 100 Mo from the present (γ, γ ) experiments are combined with (γ, n) data from literature, resulting in a photoabsorption cross section covering the range from 4 to about 15 MeV of interest for network calculations in nuclear astrophysics. Novel information about the low-energy tail of the giant dipole resonance and its energy dependence is derived. The photoabsorption cross sections deduced from the present photon-scattering experiments are compared with existing data from neutron capture and 3 He-induced reactions.
