“…These along with the lowest 7/2 − , which is the only negative-parity state strongly populated in the β decay of 109 Rh, and the 5/2 + 2 state, which has a dominant β-feeding intensity systematically across the Pd chain [21,[25][26][27][28][29][30], are highlighted below. A.…”

“…Single-neutron transfer [21,[24][25][26][27][28][29] and high spin studies [41][42][43][44][45][46][47][48] indicate that one of these levels consistently displays a νg 7/2 single-particle character, while the other can be described as a νd 5/2 ⊗ 2 + 1 configuration. This distinction is based on the observed spectroscopic strengths (Table II) and band structures connected to them (Fig.…”

“…Note that the groundstate spins and parities for the Pd isotopes in this mass range are all 5/2 + . Of particular interest from a nuclear structure standpoint are the 7/2 + states which appear in pairs at relatively low energies systematically across the Pd isotope chain [21][22][23][24][25][26][27][28][29][30] and seem to display two distinct structures. Other levels of interest are the lowest 7/2 − , which is the only negative-parity state strongly populated in the β decay of 109 Rh, and the 5/2 + 2 state, which has a dominant β-feeding intensity systematically across the Pd isotopic chain [21,[25][26][27][28][29][30].…”

New lifetime measurements inPd109and the onset of deformation atN=60

et al. 2015

Several new sub-nanosecond lifetimes were measured in 109 Pd using the fast-timing βγγ(t) method. Fission fragments of the A=109 mass chain were produced by bombarding natural uranium with 30 MeV protons at the Jyväskylä Ion Guide Isotope Separator On-Line (IGISOL) facility. Lifetimes were obtained for excited states in 109 Pd populated following β decay of 109 Rh. The new lifetimes provide some insight into the evolution of nuclear structure in this mass region. In particular, the distinct structure of the two low-lying 7/2 + states occurring systematically across the Pd isotopic chain is supported by the new lifetime measurements. The available nuclear data indicate a sudden increase in deformation at N =60 which is related to the strong p-n interaction between πg 9/2 and νg 7/2 valence nucleons expected in this region.

Feeding of Rh and Ag isomers in fast-neutron-induced reactions

et al. 2016

Background: In (n, n ′ ) reactions on stable Ir and Au isotopes in the mass A = 190 region the experimentally established feeding of the isomers relative to the feeding of the corresponding ground states increases with increasing neutron energy up to the neutron energy where the (n, 2n) reaction channel opens up and then decreases.Purpose: In order to check for similar behavior in the mass A = 100 region the feeding of isomers and ground states in fast-neutron-induced reactions on stable isotopes in this mass region was studied. This is of especial interest for Rh which can be used as a radiochemical detector.Methods: Excited states were studied using the (n, n ′ γ), (n, 2nγ) and (n, 3nγ) reactions on 103 Rh and 109 Ag. A germanium-detector array for γ-ray detection and the broad-spectrum pulsed neutron source of the Los Alamos Neutron Science Center's Weapons Neutron Research facility were used for the measurement. The energy of the incident neutrons was determined using the time-of-flight technique.Results: Absolute partial γ-ray cross sections were measured for 57 transitions feeding isomers and ground states in 101,102,103 Rh and 107,108,109 Ag. The feeding of the isomers was found to be very similar in the corresponding reaction channels and it is compared to the feeding determined for the ground states. Conclusions:The opening of reaction channels at higher neutron energies removes angular momentum from the residual nucleus and reduces the population of the higher-spin isomers relative to the feeding of the lower-spin ground states. Similar behavior was observed in the mass A = 190 region in the feeding of higher-spin isomers, but the reverse behavior was observed in 176 Lu with a lower-spin isomer and a higher-spin ground state.PACS numbers: PACS number(s): 25.40.-h, 28.20.-v, 24.10.-i, 25.40.Fq * fotia@lanl.gov 2

Antimony‐119 (119Sb) holds promise for radiopharmaceutical therapy (RPT), emitting short‐range Auger and conversion electrons that can deliver cytotoxic radiation on a cellular level. While it has high promise theoretically, experimental validation is necessary for 119Sb in vivo applications. Current 119Sb production and separation methods face robustness and compatibility challenges in radiopharmaceutical synthesis. Limited progress in chelator development hampers targeted experiments with 119Sb. This review compiles literature on the toxicological, biodistribution and redox properties of Sb, along with existing Sb complexes, evaluating their suitability for radiopharmaceuticals. Sb(III) is suggested as the preferred oxidation state for radiopharmaceutical elaboration due to its stability in vivo and lack of skeletal uptake. While Sb complexes with both hard and soft donor atoms can be achieved, Sb thiol complexes offer enhanced stability and compatibility with the desired Sb(III) oxidation state. For 119Sb to find application in RPT, scientists need to make discoveries and advancements in the areas of isotope production, and radiometal chelation. This review aims to guide future research towards harnessing the therapeutic potential of 119Sb in RPT.
