We consider 1s Auger decay in doubly (core-core and core-valence) ionized Ne and in the isoelectronic first row element hydrides. We show theoretically that the presence of the spectator inner valence vacancy leads to Auger lifetime variation of up to about a factor of 2, relative to the Auger lifetimes in the singly ionized species. The origin of this effect is traced to spin selection rules. Implications on the modelling of the radiation damage in strong x-ray fields are discussed.
我们研究了双电离（芯-芯和芯-价）的 Ne 原子以及等电子的第一主族氢化物中的 1s 俄歇衰减。我们从理论上表明， spectator 内价空位的存在会导致俄歇寿命相对于单电离物种的俄歇寿命发生高达约 2 倍的变化。这种效应的起源可以追溯到自旋选择定则。讨论了其对强 X 射线场中辐射损伤建模的影响。
