Summary on Grant Application Form
The advent of radioactive nuclear beams, combined with state-of-the-art nuclear spectrometers, gives unprecedented access to a range of exotic nuclear states. We propose to exploit newly developed, experimental facilities in Europe, to study a selection of phenomena that probe the nuclear mean-field paradigm and require explicit account of nucleon-nucleon interactions. Part of our work will be to study the growth of collective phenomena as both neutrons and protons are added to the doubly-closed-shell 208 Pb core. In relatively light nuclei the emphasis is on the way that the closed shell for 20 neutrons itself is dependent on the number of protons. The interactions between neutrons and protons have a very special form when the numbers of neutrons and protons are equal, and we will study the consequent neutron-proton pairing effect in the heaviest possible odd-odd nuclei of this type that may now be accessed. The production of nuclei at high excitation energy and high angular momentum also opens novel avenues: we will exploit high-spin isomers, produced by projectile fragmentation, to measure nuclear shapes by Coulomb excitation. All of these measurements will lead to a new understanding of nuclear stability, nucleon-nucleon correlations, and the interplay between individual-particle and collective degrees of freedom in the many-fermion, mesoscopic domain of atomic nuclei.
