允許躍遷 的英文怎麼說
中文拼音 [yǔnxǔyuèqiān]
允許躍遷
英文
allowed transition-
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。Then we focus on the relationship between the current and the transition width. for small temperature, as well as for very high temperature the current does not inflect with the change of the transition width. at the appropriate temperature, the current increases with the transition width increasing
然而在適當的溫度范圍內，允許粒子在一定寬度內躍遷，粒子在這一范圍內出現幾率增加，就使得更多的粒子躍遷幾率增加，產生了較大的幾率流。
