forbidden decay 中文意思是什麼

forbidden decay 解釋
禁戒衷減
  • forbidden : adj. 被禁止的。
  • decay : vi. 1. 朽,腐爛。2. 衰減,衰退。3. 凋謝,枯。vt. 使朽壞;使衰退。n. 1. 衰微,衰退。2. 朽,腐爛。3. 【無線電】衰變。
  1. Otherwise, decay process is forbidden.

    如果不是這樣,就不會發生這樣的衰變。
  2. 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。
