TL;DR: In this article, the authors obtained energy and γ -ray branching ratios for 208 Pb levels below 7.5 MeV and combined with known spectroscopic factors and radiation widths give information on level assignments and correlations of E1 radiation and neutron strengths.

TL;DR: In this article, a new technique for the study of the beta rays emitted by polarized nuclei is presented, which uses two silicon detectors arranged in coincidence so as to discriminate against gamma rays and back scattering from the detectors.
Abstract: A new technique for the study of the beta rays emitted by polarized nuclei is presented. This technique uses two silicon detectors arranged in coincidence so as to discriminate against gamma rays and back scattering from the detectors. This technique has been used to study the asymmetry of the beta rays in the decay of $^{110m}\mathrm{Ag}$.

TL;DR: In this paper, a simple method for growing massive single crystals of the alloy series SnTe-GeTe, suitable for inelastic neutron studies, is described, and a table of the time-temperature cycle is provided.

TL;DR: The thermal neutron target of the recent Intense Neutron Generator (ING) project at Chalk River Nuclear Laboratories was to incorporate a lead-bismuth eutectic circuit passing through a moderator tank containing heavy water.
Abstract: The thermal neutron target of the recent Intense Neutron Generator (ING) project at Chalk River Nuclear Laboratories was to incorporate a lead-bismuth eutectic circuit passing through a moderator tank containing heavy water. The section of the circuit in the tank was to be made of a zirconium alloy, to minimize thermal neutron absorption. Various protective coatings insoluble in lead-bismuth eutectic were considered. The literature on bismuth and lead-bismuth suggested that a low chromium-molybdenum steel would be suitable for the external circuit, but possibly only if the lead-bismuth was thoroughly de-oxidised and treated with zirconium or titanium.[1, 2]
