在重离子储存环上对铁族元素的Al-、Si-、P-和S-类离子的3s 23 pk基态组态能级的原子寿命数据进行了可靠的网格化，对Cl、Ti、Mn、Cu和Ge离子的电偶极禁戒衰变进行了测量，补充了以前对Fe、Co、Ni和Cu离子的测量。的数据进行了比较等电子与各种预测，特别是那些由多参考Møller-Plesset技术，并与其他实验方法提供的少数结果。明显的扰动，否则顺利的等电子趋势的一些数据被确定与特定的级联从长寿命的3d水平的发生。
Working towards a reliable grid of atomic lifetime data on 3s23pk ground configuration levels of Al-, Si-, P-, and S-like ions of iron group elements, measurements on electric-dipole forbidden decays in ions of Cl, Ti, Mn, Cu, and Ge have been done at a heavy-ion storage ring that complement earlier measurements on Fe, Co, Ni, and Cu ions. The data are compared isoelectronically with various predictions, especially those made by the multi-reference Møller–Plesset technique, and with the few results available from other experimental approaches. Apparent perturbations of otherwise smooth isoelectronic trends of some of the data are identified with the occurrence of specific cascades from long-lived 3d levels.
