The aim is to study exotic long-lived states in nuclei using accelerator facilities in Australia and overseas. This involves the development of sensitive instrumentation and will lead to a new understanding of how such states are formed, of how they may be used to identify the structure of exotic nuclei, and on the limits of stability of nuclei in general. Isomers represent a special form of nuclear matter and they play a role in the formation of the elements in stellar nucleosynthesis. Stimulated isomer decay may ultimately lead to new forms of energy storage and gamma-ray lasers.

其目的是利用澳大利亚和海外的加速器设施，研究原子核中奇异的长寿命态。这涉及开发灵敏的仪器，并将导致对这种状态是如何形成的、如何利用它们来确定奇异核的结构以及一般核的稳定性限度的新的理解。异构体代表了核物质的一种特殊形式，它们在恒星核合成中元素的形成中发挥了作用。受激异构体衰变可能最终导致新形式的能量存储和伽马射线激光。
