A persistent theme is science is to investigate the behaviour of physical systems under extreme conditions. The quest to observe increasingly high angular momentum states has driven the field of gamma-ray spectroscopy for many years.Each step forward in detector technology has enabled an increasingly rich variety of phemomena to be observed. This proposal aims to study nuclei at the highest possible spins. Such a study will cover a range of physics interests. The main aim is to investigate the demise of nuclear pairing correlations as the angular momentum is increased. Ananagous to a superconductor in a magnetic field, nuclear parirng correlations are expected to be quenched at high enough rotational frequency. We aim to study this phenomena through the oberservation of unparied rotational bands and unpaired crossings and identify the collapse of both neutron and proton pairing corelations. Investigations will be focussed in the mass 160 region where the highest spin states have been observed experimentally.We also aim to identify and study the states that feed the classic favoured band terminating states in 158Er. This will establish nature of high spin core excitations relative to the 146Gd core and the detatiled single particle structure at very high spin. We will also study the effects of valence space exhaustion in the smooth band termination sequences in the mass 100 region and in superdeformed 132Ce. These studies are now possible with the latest generation of gamma-ray spectrometers, namely Euroball and Gammasphere, both of which will be used in this joint proposal with the University of Liverpool.
