Key Objectives
- Investigate the role of first-forbidden transitions in the β decay of N~126 nuclei to better model the nuclear theories used for r-process nucleosynthesis calculations
- Test the seniority scheme in 1đg9/2 nuclei beyond N=126
- Study the interplay between nucleons and collective nuclear vibrations beyond N=126
- Measure spin isomers in the odd-mass Au isotopes with N>126
- Extend the systematics of first excited 2+ states in neutron-rich Pb and Po isotopes
- Obtain isomeric ratios of 238U fragmentation residues in the south-east quadrant of 208Pb to test abrasion-ablation models.
- Develop a new implanter layer as a proof of concept for the next generation of active stoppers in international fragmentation facilities
