“…The resulting time series displayed in Figures 7a -7d allow the fitting of exponential decay functions for each nuclide and comparison of the measured half-life with literature values. The fitted functions for each transition agree (at the 1σ confidence level) with accepted half-lives [10,5,27,28,30], confirming the respective peak assignments.…”

“…For the 64 Cu production experiments, the Indium foil was first counted separately using an 80% HPGe detector, to capture the short-lived Indium activities. This is due to the fact that the contaminant 115 In(n,γ) reaction results in the production of 116m In which has a 54 minute half-life and results in the production of 1097 keV (58.5% branching), 1293 keV (84.8% branching) and 2112 keV (15.09% branching) gamma-rays that in turn produce a significant number of 511 keV gammas from pair-production followed by annihilation [30]. The foils were counted together again after approximately 4 hours of separate collection, to allow for nearly all of the produced 116 In to decay.…”

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.

“…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.

An in-trap decay spectroscopy setup has been developed and constructed for use with the TITAN facility at TRIUMF. The goal of this device is to observe weak electron-capture (EC) branching ratios for the odd-odd intermediate nuclei in the ββ decay process. This apparatus consists of an upto 6 Tesla, open-access spectroscopy ion-trap, surrounded radially by up to 7 planar Si(Li) detectors which are separated from the trap by thin Be windows. This configuration provides a significant increase in sensitivity for the detection of low-energy photons by providing backing-free ion storage and eliminating charged-particle-induced backgrounds. An intense electron beam is also employed to increase the charge-states of the trapped ions, thus providing storage times on the order of minutes, allowing for decay-spectroscopy measurements. The technique of multiple ion-bunch stacking was also recently demonstrated, which further extends the measurement possibilities of this apparatus. The current status of the facility and initial results from a 116 In measurement are presented.
