8. Nuclear spectroscopy Nuclear Astrophysics: Weak interaction:
Decay properties and binding energies of rp-process nuclei
2002: 69Kr decay to 69Br
2003: Mass of 68Se and 72Kr
: 12C(a,g)16O via 17Ne(bp)
Weak interaction:
2002: High-precision studies of superallowed beta decay of 74Rb
2003: Isospin symmetry probed by the charge-exchange reactions and the beta decay of 58Zn
Structure of nuclei far from stability:
: The structure of heavy Ca-isotopes and the effective interaction in the sd-fp shell of very neutron-rich nuclei
: Evolution of collectivity in neutron-rich Cd isotopes;
change over from isospin symmetric multiplets to shell model interpretation
Exotic decay modes:
2002: Three a-cluster states in 12C
: 17Ne beta-delayed charged-particle decay
