Nuclear structure from radioactive decay

The most important aspect of the wind-up of UNISOR-based research is completion of student theses. Analysis is proceeding on extensive studies in the neutron-deficient rare earth isotopes with N < 82 and the neutron-deficient region below Z = 82. These studies address the onset of deformation in the N < 82, Z > 50 open shell region and shape coexistence in the N ∼ 104, Z ≤ 82 region, respectively. The main ongoing topics are shape coexistence in nuclei and the microscopic structure of collective motion in nuclei from a phenomenological point of view. New topics this year focus on the structure of nuclei near the N = Z line. Two topics have been chosen for detailed study: shape coexistence and electric monopole transition strengths
