Amongst the most fundamental charateristics of an atomic nucleus are the shape and size of its ground state configuration. As, in general, this is the form that the nucleus resides for the vast majority of its lifetime it appears logical to study this in order to further the understanding of nuclear structure away from the stable isotopes. For many years laser spectroscopy has been seen as one of the most powerful and sensitive methods with which to perform these studies. When coupled to a radioactive beam facility it allows for the extraction of precise systematic effects to be studied along chains of isotopes without the requirement for in-depth knowledge of either of the absolute nuclear of atomic wavefunctions.

原子核最基本的特征之一是其基态构型的形状和大小。一般来说，这是原子核在其生命的绝大多数时间内所处的形式，因此研究这一点似乎是合乎逻辑的，以便进一步了解原子核结构远离稳定同位素。多年来，激光光谱学一直被视为进行这些研究的最强大和最灵敏的方法之一。当耦合到放射性束设施时，它允许提取精确的系统效应，以便沿着同位素链进行沿着研究，而不需要深入了解原子波函数的绝对核。
