Structure of 188TI

Full text: Most recent studies of shape coexistence in the very light Z - 82 nuclei have concentrated on the even-even Hg, Pb and Po isotopes. In contrast, little is known about the close-lying odd-odd nuclei. While partly expected to resemble their neighbours, the presence of unpaired protons and neutrons can provide insight into the active single-particle orbitals and they may also affect the relative energies of the shape co-existing minima. The 188TI nuclei were studied in two experiments utilising the Gammasphere (LBNL, USA) and CAESAR (ANU, Canberra) spectrometers. The observed structures and associated intrinsic configurations which significantly extend the earlier knowledge, will be discussed. Copyright (2005) Australian Institute of Physics
