Lecture 33 - Stimulated Absorption
... ii. Stimulated absorption occurs when a photon strikes an atom with just exactly the proper energy to induce an electronic transition between two energy states. iii. Einstein’s contribution was to show that there was a third process, stimulated emission, which could cause a downward electronic trans ...

... 1913: An isolated atom consists of a positively charged nucleus about which electrons are distributed in successive orbits. He also postulated that only those orbits occur for which the angular momentum of the electron is an integral multiple of h/2p, i.e. n*h/2p, where n is an integer and h is Plan ...
