“…Now we remark that Eq. (20) in the variable φ is solved under the periodic boundary condition ϕ(φ + 2π) = ϕ(φ). On the other hand the assumption β 2 > 0, which is equivalent to the consideration of an infinite potential wall at β 2 = 0 (or φ = ±π/2), imposes the additional condition…”

Nuclear collective motion with a coherent coupling interaction between quadrupole and octupole modes

et al. 2006

View full text Add to dashboard Cite

A collective Hamiltonian for the rotation-vibration motion of nuclei is considered, in which the axial quadrupole and octupole degrees of freedom are coupled through the centrifugal interaction. The potential of the system depends on the two deformation variables β 2 and β 3 . The system is considered to oscillate between positive and negative β 3 -values, by rounding an infinite potential core in the (β 2 , β 3 )-plane with β 2 > 0. By assuming a coherent contribution of the quadrupole and octupole oscillation modes in the collective motion, the energy spectrum is derived in an explicit analytic form, providing specific parity shift effects. On this basis several possible ways in the evolution of quadrupole-octupole collectivity are outlined. A particular application of the model to the energy levels and electric transition probabilities in alternating parity spectra of the nuclei 150 Nd, 152 Sm, 154 Gd and 156 Dy is presented.

“…Thus, some unknown γ rays were assigned to 174 Re, such as the 188-, 388-, and 465-keV lines. It should be noted that the well-established high-spin level schemes for 152 Sm [22], 173,175 Re, 171 Ta [23], and 174 W were very useful for the assignment of new γ rays to 174 Re.…”

High-spin states in odd-odd174Re

et al. 2012

High-spin states in the odd-odd 174 Re have been investigated via the 152 Sm( 27 Al, 5nγ ) 174 Re reaction with the help of excitation function, x-γ , and γ -γ coincidence measurements. Five rotational bands have been observed and their configurations were assigned based on alignments, band crossing frequencies, electromagnetic properties, and the estimated bandhead excitation energies. Low-spin signature inversion has been identified in the two-quasiparticle bands built on πh 11/2 ⊗ νi 13/2 , πh 9/2 ⊗ νi 13/2 , and π 1/2 − [541] ⊗ ν5/2 − [512] configurations. E2 interband transitions were analyzed with band-mixing calculations giving information on shapes and shape driving effects for the bands of interest.

“…Calibration for energies and intensities of lines in the 152 Eu m,g decay was achieved internally; i.e., use was made of the fact that the strong lines in the 152 Eu g decay serve [12] as a secondary γ -ray energy and intensity calibration source. Peak areas were fitted in all spectra using the program GF3 [13].…”

The decays of 152 Eu m,g → 152 Sm have been studied by γ -ray spectroscopy using the 8π spectrometer, an array of 20 Compton-suppressed Ge detectors. Very weak γ -decay branches in 152 Sm were investigated through γ -γ coincidence spectroscopy. All possible E2 transitions between states below 1550 keV with transition energies >130 keV are observed, including the previously unobserved 2 + 3 → 0 + 2 401 keV transition. The results, combined with existing lifetime data, provide a number of new or revised E2 transition strengths which are critical for clarifying the collective structure of 152 Sm and the N = 90 isotones.
