“…Information was taken from the appropriate Nuclear Data Sheets covering the above Pt mass region for A = 172 [47], A = 174 [48], A = 176 [49], A = 178 [50], A = 180 [51], A = 182 [52], A = 184 [53], A = 186 [54], A = 188 [55], A = 190 [56], A = 192 [57] and, A = 194 [58]. Moreover, we also incorporate data on those even-even Pt nuclei that have been published (see below) since the latest updates of the corresponding Nuclear Data Sheets.…”

“…Here, we include the relative B(E2) values and for these data we have used a relative error of a 20%. The experimental data that we have used are taken from the Nuclear Data Sheets (NDS), Adopted Values references [47,48,49,50,51,52,53,54,55,56,57,58], unless the latest issue was published more than 10 years ago. Therefore, for the mass number A = 182, 184 and 192, the experimental data were taken from [66,79,71], respectively.…”

The role of intruder configurations in the description of energy spectra and B(E2) values in the Pt region is analyzed. In particular, we study the differences between Interacting Boson Model calculations with or without the inclusion of intruder states in the even Pt nuclei 172−194 Pt. As a result, it shows that for the description of a subset of the existing experimental data, i.e., energy spectra and absolute B(E2) values up to an excitation energy of about 1.5 MeV, both approaches seem to be equally valid. We explain these similarities between both model spaces through an appropriate mapping. We point out the need for a more extensive comparison, encompassing a data set as broad (and complete) as possible to confront with both theoretical approaches in order to test the detailed structure of the nuclear wave functions. 21.60.Fw.

“…The isotope 186 Re (half-life T 1/2 = 3.7186 d [10]) has medical applications as a high specific-activity β − emitter for the palliative treatment of bone metastases resulting from prostate and breast cancers [11]. For this purpose, 186 Re is generally produced by thermal-neutron capture on enriched 185 Re at reactors [12].…”

Partial γ-ray production cross sections and the total radiative thermal-neutron capture cross section for the 185 Re(n, γ) 186 Re reaction were measured using the Prompt Gamma Activation Analysis facility at the Budapest Research Reactor with an enriched 185 Re target. The 186 Re cross sections were standardized using well-known 35 Cl(n, γ) 36 Cl cross sections from irradiation of a stoichiometric nat ReCl3 target. The resulting cross sections for transitions feeding the 186 Re ground state from low-lying levels below a cutoff energy of Ec = 746 keV were combined with a modeled probability of ground-state feeding from levels above Ec to arrive at a total cross section of σ0 = 111(6) b for radiative thermal-neutron capture on 185 Re. A comparison of modeled discrete-level populations with measured transition intensities led to proposed revisions for seven tentative spin-parity assignments in the adopted level scheme for 186 Re. Additionally, 102 primary γ-rays were measured, including 50 previously unknown. A neutron-separation energy of Sn = 6179.59(5) keV was determined from a global least-squares fit of the measured γ-ray energies to the known 186 Re decay scheme. The total capture cross section and separation energy results are comparable to earlier measurements of these values.

“…3 is assumed to be solely representative of the yrast 2 + half-life. This assumption can be shown to be reasonable by comparison with 186 W, in which the measured half-lives of the yrast 4 + and the second 2 + state state are 36.4(25) ps and 4.78(16) ps, respectively [14]. The half-lives of the equivalent states in 188 W can be expected to be of the same order-of-magnitude.…”

The half-life of the yrast I π = 2 + state in the neutron-rich nucleus 188 W has been measured using fast-timing techniques with the HPGe and LaBr 3 :Ce array at the National Institute of Physics and Nuclear Engineering, Bucharest. The resulting value of t 1/2 = 0.87(12) ns is equivalent to a reduced transition probability of B(E2; 2 + 1 → 0 + 1 ) = 85(12) W.u. for this transition. The B(E2; 2 + 1 → 0 + 1 ) is compared to neighboring tungsten isotopes and nuclei in the Hf, Os, and Pt isotopic chains. Woods-Saxon potential energy surface (PES) calculations have been performed for nuclei in the tungsten isotopic chain and predict prolate deformed minima with rapidly increasing γ softness for [184][185][186][187][188][189][190][191][192] W and an oblate minimum for 194 W.
