“…The inability to discern both the fully Doppler-shifted and degraded components of a γ -ray transition at this angle required gates to be placed across the full widths of the transitions C. Placing gates in this way introduces an element of background into the measured intensities of each peak, A and B. However, provided that both the feeding and depopulating transitions are included in the analysis, this element of background can be eliminated [27][28][29].…”

Lifetime measurements have been made in the neutron-deficient nucleus 109 Te using the coincident recoil distance Doppler-shift method. The experimental B(E2) values have been compared with state-of-the-art shellmodel calculations using the monopole-corrected realistic charge-dependent Bonn nucleon-nucleon potential. Lifetimes in the νh 11/2 band are consistent with an interpretation based on the deformation driving properties of a single valence neutron outside of the even-even tellurium core and highlight the unexpected presence of collective behavior as the N = 50 shell closure is approached. Lifetime measurements for the low-lying positive-parity states also appear to correlate well with shell-model calculations. In addition, a comparison with the proton-unbound nucleus 109 I suggests that the presence of a single decoupled valence proton affects the total measured B(E2) strengths in a manner that is not currently well understood.

“…The existence of rather pure rotational bands is confirmed for nuclei where both ␤ 2 ͑t͒ and ␤ 2 ͑s͒ have close values. To the best of our knowledge, there are no experimental data for B͑E2͒ values in neutron-deficient Pb isotopes, except the very recent measurements in 188 Pb of Dewald et al [41]. The B͑E2͒ value measured for the 4 1 + → 2 1 + transition is equal to 160 W.u.…”

Configuration mixing of angular momentum projected self-consistent mean-field states for neutron-deficient Pb isotopes

et al. 2004

We study the low-lying collective excitation spectra of the neutron-deficient lead isotopes [182][183][184][185][186][187][188][189][190][191][192][193][194] Pb by performing a configuration mixing of angular momentum and particle-number projected self-consistent meanfield states. The same effective interaction is used to generate the mean-field states and for the configuration mixing. We choose the Skyrme interaction SLy6 supplemented by a density-dependent zero-range pairing force. Our study supports the interpretation of the excitation spectra made on the grounds of more schematic models in terms of coexisting spherical, oblate, prolate, and superdeformed prolate structures. The model qualitatively reproduces the variation of the spectra with neutron number. Our results for E0 and E2 transition probabilities are compared with the few existing experimental data. Finally, we predict the presence of superdeformed bands at low excitation energy in the most neutron-deficient isotopes.

“…The efforts of several research groups have made detailed experimental data such as energy spectra, electromagnetic decay properties and isotopic shifts available (see Refs. [7,8,9,10,11,12,13] for the most recent articles and Ref. [3] and references therein for a review article) .…”

In this article we report the results of detailed interacting boson model calculations with configuration mixing for the neutron-deficient Pb isotopes. Calculated energy levels and B(E2) values for 188−196 Pb are discussed and some care is suggested concerning the current classification on the basis of level systematics of the 4 + 1 and 6 + 1 states in 190−194 Pb. Furthermore, quadrupole deformations are extracted for 186−196 Pb and the mixing between the different families (0p-0h, 2p-2h, and 4p-4h) is discussed in detail. Finally, the experimental and the theoretical level systematics are compared.
