Summary of expertise

  • Structure of exotic nuclei
  • Defomation and collectivity in self-conjugate nuclei
  • Neutron-proton pairing
  • Isomeric states in nuclei



My current research is focused on studies of nuclei with approximately equal numbers of protons and neutrons. Recent work has involved the investigation of nuclear shapes and deformations of N=Z nuclei, isospin symmetry, neutron-proton pairing and nuclear isomeric states and their decays just below 100Sn.  Some of the latest publications in these areas include studies of isospin symmetry in T=1 states in the mass 70 nuclei, a study of the role of nucleon core-excitations on the structure and decay modes of the 16+ spin-gap isomer in 96Cd,  investigation of shape co-existence and shape transition through the impact of the tensor force in the self-conjugate nucleus 72Kr and the discovery and structural interpretation of a proton decaying  isomeric state in 72Rb - a nucleus that resides beyond the proton drip-line.


Spectroscopy of proton rich nuclei using fragmentation, nucleon knock-out, low energy Coulomb excitation and fusion evaporation reaction techniques.

Experiments are performed at RIKEN, NSCL, ISOLDE, GANIL and Jyvaskyla.
