Tiivistelmä
The proposed project is aimed at improving our understanding of the proton-neutron interaction by probing, using optical techniques, proton-rich nuclei with N~Z and mass close to A=100. Such nuclei are ideal laboratories due to a large spatial overlap between the single-particle wave functions arising from the occupation of the same shell-model orbitals. Nevertheless, their experimental study has been hindered due to very low production cross sections and an often overwhelming "hostile" environment of unwanted contaminant reaction products.
In order to study the key nuclei, it is necessary to develop state-of-the-art instrumentation and to combine a large number of experimental techniques in a unique manner. A complex combination of recoil separator, stopping gas cell, mass spectrometer and resonant laser spectroscopy will be employed. By probing atomic hyperfine structures and isotope shifts, fundamental properties of the nucleus may be measured in a model-independent manner. These include a direct determination of the nuclear spin, electromagnetic moments and changes in mean-squared charge radii. These properties will then be tested against a range of state-of-the-art theoretical approaches, from large-scale shell model calculations, to ab-initio and mean field approaches.
