Tiivistelmä
The actinide elements offer abundant opportunities for multidisciplinary science, ranging from nuclear structure physics and atomic physics, to the search for physics beyond the Standard Model. The goal of this Academy project is to advance knowledge on the actinide nuclei by utilizing state-of-the-art techniques, both experimentally and theoretically. On the experimental side, this project plans to probe various ground-state properties of light actinide elements by combining radioactive beam science with in-gas-cell resonance ionization spectroscopy at the IGISOL facility at the Accelerator Laboratory of the University of Jyväskylä. Through measurements of the perturbations of atomic levels, information about the nuclear charge radius, nuclear spin, shape and magnetic
moment can be extracted in a model-independent manner.
Theoretically, this experimental information provides important input to test existing theoretical nuclear structure models, based on the nuclear density functional theory (DFT). This enables the pinpointing of deficiencies in current models. The main theoretical goal is to construct a new energy density functional (EDF), a key ingredient in DFT, with a high predictive power, especially tailored for the actinide region. The experimental information obtained during this project provides input and validation data for this task. Due to the universality of the EDF models, the developed functional can be applied throughout the nuclear chart, offering a wide range of possible applications. One particularly interesting application will be the computation of the nuclear Schiff moment, which is connected to the experimental search for the atomic dipole moment and physics beyond Standard Model.
