The interaction between the energized electron and the hole it leaves behind is called an exciton, and the difference in energy levels between the hole and the electron is known as the bandgap.

这种获得能量的电子和他留在原来能级上对应的位置的空穴的相互作用叫做一个激子激发过程，而这两个不同能级之间的部分被称作带隙。

By using the electron correlated basis function of excited state, we calculate the effect of electron interaction on the bandwidth of conductive polymers.

So, we just talked about the force law to describe the interaction between a proton and an electron. You told me that when the distance went to infinity, the force went to zero. What happens instead when the distance goes to zero? What happens to the force?

我们刚刚讨论了描述质子,和电子之间相互作用力的定律,当距离变为无穷时,力变为零，那当距离变为,零时会发生什么？,这时候力是多少？

If and when a neutrino does bump into something, the interaction spits out one of three particles an electron, a muon or a tau (the last two are heavy, unstable objects with most of the characteristics of an electron).
