“…The coexistence of the first and third harmonic gave us the opportunity to calibrate the energy scale using the Sn K-edge (29.2004(2) keV [38]). The resonance energy for the 99 Ru first excited state was found to be 89.571(3) keV, in excellent agreement with the tabulated value, 89.57(6) keV [39]. In order to avoid detector overload in the forward direction, the 29.8 keV radiation was filtered out by a 200 µm Sn foil [40].…”

“…In all even-nuclei examined here, K was taken as zero, whereas for the odd nuclei the bandhead value of K was used. Since it is usually difficult to determine the centroid energy of the Doppler-broadened lineshapes to a level of accuracy comparable to experiments that produce narrow lineshapes, we have consistently used the evaluated γ-ray energies [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41] in our fits and calculations of the state lifetimes.…”

The Eurogam-2 array has been used to study γ rays emitted following the spontaneous fission of a 248 Cm source. Analysis of Doppler-broadened lineshapes corresponding to transitions from excited rotational states in neutron-rich Sr, Zr, Mo, Ru and Pd fission fragments has enabled measurements of state lifetimes in these nuclei at nuclear spins of I ∼ 10. Extracted transition quadrupole moments are compared with various recent theoretical approaches, as well as with measurements at lower spin, and an interpretation of the data is made within the context of prolate-oblate shape competition in this region.

“…This radionuclide is attractive as an emerging diagnostic isotope, due to the similarity of the emitted gamma ray to that of the well-established 99m Tc [11,12,13,14]. Due to the short half-life (t 1/2 = 6.0 h) of and dwindling supplies of 99m Tc, 47 Sc stands poised as a potential solution to this shortage, due to its longer half-life and multiple production pathways without the need for highly enriched uranium [15]. In addition, when paired with 44 Sc, 47 Sc forms a promising "theranostic" pair for use in simultaneous therapeutic and diagnostic applications [16,17].…”

Cross sections for the 47 Ti(n,p) 47 Sc and 64 Zn(n,p) 64 Cu reactions have been measured for quasi-monoenergetic DD neutrons produced by the UC Berkeley High Flux Neutron Generator (HFNG). The HFNG is a compact neutron generator designed as a "flux-trap" that maximizes the probability that a neutron will interact with a sample loaded into a specific, central location. The study was motivated by interest in the production of 47 Sc and 64 Cu as emerging medical isotopes. The cross sections were measured in ratio to the 113 In(n,n') 113mIn and 115 In(n,n') 115mIn inelastic scattering reactions on co-irradiated indium samples. Post-irradiation counting using an HPGe and LEPS detectors allowed for cross section determination to within 5% uncertainty. The 64 Zn(n,p) 64Cu cross section for 2.76 +0.01−0.02 MeV neutrons is reported as 49.3 ± 2.6 mb (relative to 113 In) or 46.4 ± 1.7 mb (relative to 115 In), and the 47 Ti(n,p) 47 Sc cross section is reported as 26.26 ± 0.82 mb. The measured cross sections are found to be in good agreement with existing measured values but with lower uncertainty (<5%), and also in agreement with theoretical values. This work highlights the utility of compact, flux-trap DD-based neutron sources for nuclear data measurements and potentially the production of radionuclides for medical applications.
