An electron (rest mass me) of energy E makes a head-on collision with a positron (positron is electron’s antiparticle, it has the same mass as electron, but opposite charge) In collision the two particles annihilate each other and are replaces by two photons (γ rays) of equal energy, each traveling at equal angles θ with electron’s direction of motion. Find 1. The energy of each photon. 2. The momentum p of each photon. 3. The angle θ. Problem 3. Electron-positron...

An electron and a positron, each moving at 3.0 x 10^5m/s, collide head on, disappear, and produce two photons moving in opposite directions, each with the same energy and momentum. Determine the energy and momentum of each photon (show your units)
An electron-positron pair is produced by a 2.30 MeV photon. What is the kinetic energy of the positron if the kinetic energy of the electron is 0.958 MeV? Use the following Joules-to-electron-Volts conversion 1eV = 1.602 × 10-19 J. The rest mass of an electron is 9.11 × 10-31 kg
5. In a linear collider, two particles travel toward each other from opposite directions before colliding. I, in the lab reference frame, an electron travels toward the collision point at 2/3 co and a positron travels at 3/4。, at what speed does the electron travel toward the positron in the positron's reference frame?
An electron-positron pair is produced by a 2.85 MeV photon. What is the kinetic energy of the positron if the kinetic energy of the electron is 1.219 MeV? Use the following Joules-to-electron-Volts conversion 1eV = 1.602 × 10-19 J. The rest mass of an electron is 9.11 × 10-31 kg Please answer in MeV
Problem 4. Electron-positron production An electron-positron pair (positron is electron’s antiparticle, it has the same mass as electron, but opposite charge) can be produced what two photon are collided. Two photons of frequency ω are collided head-on. What will be the electron’s momentum? Electron’s rest mass is me.
When a fast electron (i.e., one moving at a relativistic speed) passes by a heavy atom, it interacts with the atom's electric field. As a result, the electron's kinetic energy is reduced, the electron slows down in the meantime, a photon of light is emitted. The kinetic energy lost by the electron equals the energy E_r of a photon of radiated light. E = K - K', where K and K' are the kinetic energies of the electron before and...
