报告简介：
Nuclear physics research is at the dawn of a new era. After the Big Bang and billions years of evolution, the universe has provided us around 2000 nuclei. Based on the information from these nuclei, nuclear theory has been established. The steady progress over the past twenty years in the development of high intensity stable beams and of beams of radioactive isotopes has allowed to vastly expand the objectives of experimental nuclear research. With more than 2000 nuclei produced artificially and around 6000 expected to be produced in the facilities in operation or under construction in China, Europe, Japan and US, nuclear physics meets serious challenges. It is becoming possible to study in the laboratory a range of nuclear reactions that take place in exploding stars providing crucial information to understand how the chemical elements that we find on Earth were formed. To achieve this ambitious goal, one needs to study the characteristics of unstable (radioactive) nuclei through their decays and the various nuclear interactions. Such unstable nuclei have also a wide range of applications including nuclear medicine, climate changes etc. In this presentation I will report on the AGATA g-ray tracking array and on the experimental campaign presently ongoing at LNL including results from the previous GANIL campaign. I will also present future programs of the new SPES ISOL radioactive ion beam facility focused on nuclear astrophysics and applications. Concerning astrophysics, we have recently measured at ANL (USA) the 85Kr (n, g) reaction using the surrogate reaction method with the HELIOS solenoidal spectrometer. Referring to application I will also report on the results of the REMO-Clim Ocean project, performed in Spain and in Italy within the EU PNRR program using radiotracers to monitor the adaptation of marine calcifying species to the new climatic conditions.

He began his career as a Researcher at INFN in 1989, becoming a First Researcher there in 1993. From 1998 to 2018, he served as Director of the Research Division at LNL. His distinguished career includes receiving the Humboldt Award (Wilhelm Bessel Award) in 2001 and becoming a Full Professor (Dirigente di Ricerca) in 2002. He was also the Scientific Director of the SPES project from 2013 to 2019 and a CERN Scientific Associate from 2020 to 2021. Most recently, he was awarded a Doctor Honoris Causa by the Bulgarian Academy of Science in 2024.

报告简介：
I shall explain why, 100 years after its discovery, it is still a topic of vital interest and a necessary tool to understand nuclear structure, especially of nuclei that lie far from the line of nuclear stability. Beta decay is of considerable importance in terms of understanding related fields such as nuclear astrophysics, the formation of the chemical elements in the Universe and neutrino physics. A knowledge of beta decay is also important in the development of technologies applied to problems of social interest such as reactor safety or medical diagnosis and treatment. I shall give some examples of the state of the art of current beta decay experiments on nuclei far from stability and an application to the diagnosis of ocean acidification.
