The existence of an uncompensated magnetic order in epitaxial thin films of multiferroic bismuth ferrite (BiFeO3 or BFO) is still the subject of intense debate. The Time Differential Perturbed Angular Correlation (TDPAC) technique monitors local fields at the atomic scale without altering the structure of the investigated materials. Using such an approach, we observed that BFO epitaxial thin...
Colour centers based on group-IV impurities (SiV, GeV, SnV, and PbV) in diamond are intensively investigated in the context of quantum nanophotonic applications, with some of their attractive properties stemming from the inversion symmetry of their split-vacancy configuration and their high Debye-Waller factor. Whereas a significant amount of research has been devoted to study their...
Tantalum targets can be used to produce lanthanide beams but in order to extract species with slow release times, such as terbium, the targets have to be pushed to extreme temperatures. This is especially true when it comes to medical isotope production that requires collections in the order of GBq/day of radionuclides with a minimum half-life of several hours. One way to volatilise the more...
The use of radionuclides for cancer diagnostics and therapy is extensively recognized and employed across various techniques. The effectiveness of these techniques, along with the minimisation of the doses to healthy tissue in both, therapy and diagnostics, hinges on several factors, one of which is the decay properties of the specific radionuclide used. Specifically, the types of particles,...
The validity of the Brink-Axel hypothesis is inferred from the resembling behaviour of giant dipole resonances built on ground and excited states, which present similar energy systematics. Together with previous work, this assigns giant dipole resonances as spectroscopic probes or “nuclear thermometers” to explore the cooling of the extremely hot ejecta gas produced in neutron-star mergers,...
