The interaction between an electron and a photon is represented by the Compton equation, published in 1923. Energy is transferred from the photon to the electron. The collision is elastic and each particle recoils in a different direction.

The interaction may be represented as three “phases” of momentum. Each phase (initial, exchange, and final) may be represented as a 3D vector of momentum.

The vectors must be “compatible” for energy transfer so that compatibility conditions apply to the vectors (see attachment). Vector components will give the Compton equation.

Is a sequence of vectors a valid way to represent a transfer of energy?

Can a sequence of vectors represent the Compton equation?
Well there's probably someone somewhere trying to represent it via interpretive dance.

The question is does it help to represent it as a sequence of vectors?
