摘要
本文简要叙述了光电效应产生的微观机理。用反证法证明了光子与自由电子之间不能发生光电效应 ,从而说明了影响光电效应截面的因素 ,指出电子的束缚能越大 ,光电效应截面就越大 。
The microcosmic mechanism of the photoelectric effect is briefly related.The conclusion that photon and free electron couldnt evolve photoelectric effect which is proved by gave a counterevidence.If the doorsill energy is high,the cross section will be large.The doorsill energy of photoelectric effect is a statistical value.
