Quantum mechanics formula derivation ~ DJψ fMψ i 2 dN f2πδE fE i where ψ fMψ iψ fMψ id 3x describes the QM transition dN. The theory of quantum mechanic was developed in the first half of the twentyth century in order to describe the physical phenomena on atomic lengthscales. Indeed recently has been searched by users around us, maybe one of you. People now are accustomed to using the internet in gadgets to see image and video data for inspiration, and according to the name of the post I will discuss about Quantum Mechanics Formula Derivation In the center of mass frame let p_1be the inbound photon p_2the inbound electron p_3the scattered photon p_4the scattered electron.
