This project will study the structure of atomic nuclei at the limits of elongation and stability. Highly elongated, or superdeformed, shapes of nuclei near lead will be studied by measuring magnetic moments of these excitations, studying the decay of these shapes to excitations with normal deformations, and extending the search for these shapes to systems which are highly likely to fission. The structure of nuclei near the region where decay by proton emission can occur will be probed by studying the magnetic moments of the ground states and the excitations built on isomers which decay by emitting a proton or alpha particle. Techniques will be developed for future studies of nuclear magnetic properties of nuclei far from stability produced as radioactive ion beams.

该项目将研究原子核在伸长和稳定性极限下的结构。 通过测量这些激励的磁矩，研究这些形状对正常变形激励的衰减，并将对这些形状的搜索扩展到极有可能发生裂变的系统，从而研究铅附近的高度拉长或超变形的核形状。 通过研究基态的磁矩和通过发射质子或阿尔法粒子衰变的异构体的激发，可以探测质子发射衰变区域附近的原子核结构。 未来将开发技术来研究远离放射性离子束产生的稳定性的原子核的核磁特性。
