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
在高離化態原子中，磁相互作用明顯增強， 「允許的」電偶極（ e1 ）躍遷將遭到來自磁偶極（ m1 ） 、電四極矩（ e2 ）和其它高次的「禁戒」躍遷的強烈競爭，禁戒躍遷幾率隨核電荷數z增加而迅速增加，此外量子電動力學效應也隨著z增加而增強。 -
Bfs sensitively probes inter - electron correlation, relativistic and quantum electrodynamics corrections, so it can be used to test the basic many - body atomic theory or interpret spectra from space. the main contents of this dissertation are as follows : 1 the history and development of beam - foil spectroscopy are reviewed, and the characteristics of bfs are also described. the main applications in the spectroscopic studies and lifetime measurement of highly ionized ions are summarized
