In-Beam Studies of 96Zr and 98Zr: Collective Excitations
Nearly two decades ago signatures of deformation in the ground state bands of 100Zr and 102Zr were identified, and the rapid change in the deformation of heavy zirconium nuclei noted.1 It is now well accepted that the short-range proton-neutron interaction between the 1g9/2 and 1g7/2 spin-orbit partners plays an important role in producing ground state deformation in this region.2 Nevertheless, recent studies of zirconium nuclei, including those in the transition region,3–10 continue to refine our understanding of the interplay between single-particle and collective degrees of freedom. In this report we discuss some aspects of the level structures of 96Zr and 98Zr with emphasis on collective excitations.
