A laser pulse can modify the electron s state so that it has the density distribution shown in green.

一束激光脉冲可以改变电子的状态，使得其有了图中绿色显示的密度分布。

But it is interesting. Let's just, for an order of magnitude say what happens for ground state electron in atomic hydrogen?

但行星模型其实挺有趣的，按照重要的先后顺序，我们来猜想一下，氢原子中的基态电子会发生些什么？

In other words, just want to know where the electron is somewhere within the shell radius of the ground state of atomic hydrogen anywhere.

换言之，我只是想知道，电子在哪，可以在氢原子基态下的半径，里面的任何地方。

When a light particle,or photon, hits an electron, the electron jumps to a higher energy state.

When an electron drops back from an excited to an unexcited state, it gives out light.

ECONOMIST: Optoelectronics

Bombard an ordinary hydrogen atom with microwaves of the right frequency and you will lift it out of its ground state by flipping the spin of its electron.

ECONOMIST: Are matter and antimatter truly opposites?

Konstantin Likharev, at the State University of New York at Stony Brook, a co-inventor of the single-electron transistor, is working on ways to combine it with conventional transistors to make super-dense memory chips.
