精确的原子寿命数据对于地球和天体物理等离子体诊断是有用的。在比这些应用所需的精度更高的精度下，寿命测量以与光谱能量测定互补的方式测试原子结构理论。在最高的精确度水平上，问题出现了，这样的测试是否达到了现代理论的极限，量子力学和QED的结合，并可能指向标准模型之外的物理学。如果高精度的原子寿命测量，特别是对多电荷离子的测量，还没有完全达到这样的高精度，那么达到这个目标需要什么呢？
Accurate atomic lifetime data are useful for terrestrial and astrophysical plasma diagnostics. At accuracies higher than those required for these applications, lifetime measurements test atomic structure theory in ways complementary to spectroscopic energy determinations. At the highest level of accuracy, the question arises whether such tests reach the limits of modern theory, a combination of quantum mechanics and QED, and possibly point to physics beyond the standard model. If high-precision atomic lifetime measurements, especially on multiply charged ions, have not quite reached this high accuracy yet, then what is necessary to attain this goal?
