但实际上我们也可以讨论氢原子,或者其它任何原子的其它能级的电离能。
But, in fact, we can also talk about the ionization energy of different states of the hydrogen atom or of any atom.
5500光年远处,猫爪星云是一个发射星云,红色来源于其丰富的电离状态的氢原子。
At 5, 500 light years distant, Cat's Paw is an emission nebula with a red color that originates from an abundance of ionized hydrogen atoms.
当所用激光辐射中的电场与氢原子中电子在基态所感受到的库仑场强度相当时会出现多光子电离现象。
The multiphoton ionization will happen when the electric field of lasers is equivalent to the Coulomb field in a hydrogen atom.
So, if, for example, we were looking at a hydrogen atom in the case where we have the n equals 1 state, so the electron is in that ground state, the ionization energy, it makes sense, is going to be the difference between the ground state and the energy it takes to be a free electron.
电离氢原子所需要的能量,如果我们看n等于1的情况,电子在基态,那电离能,很合理的就是基态,和自由电子态的能量差。
