核电荷数 meaning in Chinese
nuclear charge number
Examples
- Nuclear charge number
核电荷数 - Highly ionized atoms have several properties that differ from those of neutral and few times ionized atoms . since the nuclear charge z greatly exceeds the charge of the remaining electrons , there are large magnetic effects
高离化态离子核外电子数远小于核电荷数z ，故其性质不同于中性或低离化态的离子。 - The " allowed " electric dipole ( el ) transitions will encounter strong competition from " forbidden " transitions , i . e . magnetic dipole ( ml ) , electric quadruple ( e2 ) and other higher order transitions , the transitions rates for the forbidden decay scale with higher powers of z than those of el transitions , the effects of quantum electrodynamics ( qed ) also scale with higher power of z . accelerator - based beam - foil spectroscopy ( bfs ) is an important method for spectroscopic studies of highly ionized atoms
在高离化态原子中，磁相互作用明显增强， “允许的”电偶极( e1 )跃迁将遭到来自磁偶极( m1 ) 、电四极矩( e2 )和其它高次的“禁戒”跃迁的强烈竞争，禁戒跃迁几率随核电荷数z增加而迅速增加，此外量子电动力学效应也随着z增加而增强。
