Beta-beams is a novel concept for the production of neutrino beams exploiting boosted radioactive ions which decay through beta-decay. Here we describe a project, currently under investigation, where such beams are used to address the issue of CP violation in the lepton sector. We also mention the interest of having low-energy beta-beams. The connection to projects for the production of very in...

Unstable atomic nuclei release excess energy through various radioactive decay processes. In some cases, including internal conversion and electron capture, the atom remains ionised after the nuclear decay event. Atomic relaxation back to the ground state occurs rapidly via radiative and non-radiative processes, often referred to collectively as atomic radiations. Non-radiative processes includ...

Abstract Decay properties known in neutral atoms can be altered significantly if all or most bound electrons are removed. Straightforwardly, fully-ionised nuclei, the decay channels involving simply disabled. Also modes, that hindered completely blocked atoms, may, respectively, become dominant open up highly charged ions. Few-electron ions by themselves clean systems with well-defined quantum ...

Soon after the Chernobyl accident, the radioactive cloud, carrying the nuclides released into the atmosphere, reached Romania and, due to the rainy weather, an important fallout occurred over the Romanian territory. The most important contaminants for Romania were I, Cs, Cs and Sr. As in many other countries, in the first days, I had the main contribution to the irradiation dose released to the...

We present the performances of Li-based compounds used as scintillating bolometer for rare decay studies such as double-beta decay and direct dark matter investigations. The compounds are tested in a dilution refrigerator installed in the underground laboratory of Laboratori Nazionali del Gran Sasso (Italy). Low temperature scintillating properties are investigated by means of different radioac...
