Question
<p>A photon of energy E strikes an electron at rest and undergoes pair production, producing a positron and an electron<br /> Photon + e<sup>-</sup> --> e<sup>-</sup> + e<sup>+</sup> + e<sup>-</sup><br />The two electrons and the positron move off with identical momenta in the direction of the initial photon. Find the kinetic energy of the three final particles and find the energy E of the photon.</p>Explanation / Answer
I get the K of electron after collision: 2/3mc^2 and for initial photon energy of: 4mc^2
