excited atom

基本解释

Both interactions of a two-level atom with a vacuum field and a excited atom with a coherent field, as examples, are discussed in detail.
作爲例子，詳細討論了二能級原子與真空場的相互作用以及処於激發態的原子與相乾場的相互作用。
Quantum electrodynamics formulas are applied to calculate the spontaneous emission rate of an excited atom in the vicinity of a perfect reflecting mirror.
利用腔量子電動力學計算了原子在全反射鏡麪附近的自發輻射率。
The spontaneous emission phenomenon of an excited atom is one of basic processes in quantum optics.
激發態原子的自發輻射現象是量子光學領域是最基本的過程之一。

So if we're talking about the fourth excited state, and we talk instead about principle quantum numbers, what principle quantum number corresponds to the fourth excited state of a hydrogen atom.
如果我們說的是,第四激發態，我們用,主量子數來描述，哪個主量子數對應了,氫原子的第四激發態？

So, what we know is happening is that were having transitions from some excited states to a more relaxed lower, more stable state in the hydrogen atom.
我們知道，這裡所發生的是,氫原子從激發態到更低更穩定的態的躍遷，而我們用眼睛可以探測到的。

So another way to say that is, in a sense, if we're thinking about the excited state of a hydrogen atom, the first excited state, or the n equals 2 state, what we're saying is that it's actually bigger than the ground state, or the 1 s state of a hydrogen atom.
換句話說，如果我們激發一個氫原子，第一激發態或者說ｎ等於２的態，我們說它比氫原子基態,或者說１ｓ態要大。

Once that is done, another laser pulse will jostle the virus from its ground state into an excited state, just as a single atom is excited by moving one of its electrons from a lower to a higher orbital.
