“…The 1957-keV level was tentatively assigned (2 + ) [16]. Angular correlation analysis of the 1180-776.5 cascade confirmed a J = 2 assignment and yielded a mixing ratio for the 1180-keV transtion of δ = 0.52 (16).…”

“…There are two β decaying states in 82 Rb, the short lived (T 1/2 =76 s) ground state with J π =1 + and a 68.9-keV longer-lived (T 1/2 =6.47 h) isomer with J π =5 − [16]. The source of our 82 Rb is from the decay of the 82 Sr parent, which due to its J π =0 + ground state and low Q value of only 180 keV, is expected to populate only the J π =1 + ground state of 82 Rb.…”

High-precisionγ-ray spectroscopy of the cardiac PET imaging isotopeRb82and its impact on dosimetry

et al. 2016

82 Rb is a positron emitting isotope used in cardiac PET imaging which has been reported to deliver a significantly lower effective radiation dose than analogous imaging isotopes like 201 Tl and 99m Tc sestamibi. High quality β-decay data are essential to accurately appraise the total dose received by the patients. A source of 82 Sr was produced at the Brookhaven Linac Isotope Producer (BLIP) then transported to Argonne National Laboratory and studied with the Gammasphere facility. Significant revisions have been made to the level scheme of 82 Kr including 12 new levels, 50 new γ-ray transitions and the determination of many new spin assignments through angular correlations. These new high quality data allow a precise reappraisal of the β-decay strength function, and thus the consequent dose received by patients.

“…Energy calibrations were done with five transitions from 137 Cs, 88 Y, and 60 Co sources ranging from 662 keV to 1.836 MeV. A calibration error of 1.5 keV and an energy resolution of 9% (6%) FWHM at 662 keV (1.332 MeV) was obtained, in agreement with the analyses from Refs.…”

γ -ray transitions between low-spin states of the neutron-rich 84,86,88 Ge were measured by means of in-flight γ -ray spectroscopy at 270 MeV/u. Excited 6 + 1 , 4 + 1,2 , and 2 + 1,2 states of 84,86 Ge and 4 + 1 and 2 + 1,2 states of 88 Ge were observed. Furthermore, a candidate for a 3 + 1 state of 86 Ge was identified. This state plays a key role in the discussion of ground-state triaxiality of 86 Ge, along with other features of its low-energy level scheme. A new region of triaxially deformed nuclei is proposed in the Ge isotopic chain.

Abstract.The neutron-rich isotopes of tungsten, osmium and platinum have different shapes in their ground states and present also shape transitions phenomena. Spectroscopic information for these nuclei is scarce and often limited to the gamma rays from the decay of isomeric states. For the neutron-rich even-even osmium isotopes 194 Os and 198 Os, a shape transition between a slightly prolate deformed to an oblate deformed ground state was deduced from the observed level schemes. For the even-even nucleus lying in between, 196 Os, no gamma ray transition is known. In order to elucidate the shape transition and to test the nuclear models describing it, this region was investigated through gamma-ray spectroscopy using the AGATA demonstrator and the large acceptance heavy-ion spectrometer PRISMA at LNL, Italy. A two-nucleon transfer from a 198 Pt target to a stable 82 Se beam was utilized to populate medium-high spin states of 196 Os. The analysis method and preliminary results, including the first life-time measurement of isomeric states with AGATA, are presented. a
