Spectral properties of nuclei near the critical point of the quantum phase transition between spherical and axially symmetric shapes are studied in a hybrid collective model which combines the $\gamma$-stable and $\gamma$-rigid collective conditions through a rigidity parameter. The model in the lower and upper limits of the rigidity parameter recovers the X(5) and X(3) solutions respectively, while in the equally mixed case it corresponds to the X(4) critical point symmetry. Numerical applications of the model on nuclei from regions known for critical behavior reveal a sizable shape phase mixing and its evolution with neutron or proton numbers. The model also enables a better description of energy spectra and electromagnetic transitions for these nuclei.Comment: 12 pages, 5 figures, 3 table

“…We report improved measurements of the thermal and resonance integral (RI) neutron capture cross sections of 171 Tm and the intensity of the 66.7 keV γ line. The thermal neutron capture cross section of 171 Tm was determined to be σ th = (9.9 ± 0.9) b (14) Based on the cadmium-difference method, we found a resonance integral of…”

Background: About 50% of the heavy elements are produced in stars during the slow neutron capture process. The analysis of branching points allows us to set constraints on the temperature and the neutron density in the interior of stars. Purpose: The temperature dependence of the branch point 171 Tm is weak. Hence, the 171 Tm neutron capture cross section can be used to constrain the neutron density during the main component of the s process in thermally pulsing asymptotic giant branch (TP-AGB) stars. Methods: A 171 Tm sample produced at the ILL was activated with thermal and epithermal neutrons at the TRIGA research reactor at the Johannes Gutenberg-Universität Mainz. Results: The thermal neutron capture cross section and the resonance integral have been measured for the first time to be σ th = 9.9 ± 0.9 b and σ RI = 193 ± 14 b. Conclusions: Based on our results, new estimations of the direct capture components' impact on the Maxwellian-nAveraged cross sections (MACS) are possible.

“…Radioactive sources of 182 Re were created using the 176 Yb( 11 B,5n) reaction with 60 MeV 11 B ions incident on a 1-mg/cm 2 enriched target. These sources were placed at the focus of the array and γ-γ and γ-e − coincidence data were collected for approximately four half-lives of the t 1/2 =64 hr, β decay into 182 W. Conversion coefficients were measured for 21 transitions in the known 182 W level scheme [16] by extracting the ratio of intensities in γ-gated γ-ray and conversion-electron spectra. In general, good agreement was found with existing literature values from Ref.…”

A new detector array, Solenogam, has been developed at the Australian National University Heavy Ion Accelerator Facility. Coupled initially to the SOLITAIRE 6.5 T, gas-filled, solenoidal separator, and later to an 8 T solenoid, the system enables the study of long-lived nuclear states through γ-ray and conversion-electron spectroscopy in a low-background environment. The detector system is described and results from the commissioning experiments are presented.
