In the atomic nucleus, the interplay between single-particle motion, collectivity and pairing is seen as a rich tapestry of coexisting nuclear shapes and exotic excitations. In order to verify and understand the shape coexistence phenomenon it is important to determine what drives nucleus into deformation, what are the underlying structures of nuclear states in the different shapes, and what are the roles of pairing, the proton-neutron interaction and configuration mixing in this picture.

The scientific aim of the present proposal is unambiguous determination of the structure of intruder states associated with different shapes in the neutron-deficient Pb region. This will be addressed using transfer reactions, only accessible with heavy radioactive beams in inverse kinematics at HIE-ISOLDE, CERN. Additional data to shed light on shape coexistence in this region will be collected in in-beam spectroscopy experiments at Accelerator Laboratory of University of Jyväskylä, Finland.
