Objectives
2 Explore novel nuclear forces and understand which properties of the nucleon-nucleon forces can modify the structural evolution in these nuclear regions. 3 Study the properties of "classical doubly magic" nuclei (78Ni and 100Sn) to provide a stringent constraint to establish reliable theories and verify a reasonable truncation for nuclear shell models making the calculation of complex nuclei feasible. 4 Study the properties of 78Ni and 100Sn, the key nuclei in rapid-proton capture (rp-) process and rapid neutron capture (r-) process in nucleonsynthesis, for better understanding of the production of heavy elements in the universe. 5 Perform in-beam gamma spectroscopy measurements for/around 54,56Ca (Z=20), 78Ni (Z=28, N=50) and 100Sn (Z=50, N=50) to achieve the physics goals. 6 Establish HKU NaI(Tl) gamma-ray detection array system which will be coupled to the existing instrumentation at the world’s leading facility in RIKEN (Japan) for the measurements, to significantly improve the detection efficiency and add-back factors.
