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.

(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

An electron and a positron each have a mass of 9.11 ×
10-31 kg. They collide and both vanish, with only
electromagnetic radiation appearing after the collision. If each
particle is moving at a speed of 0.42c relative to the
laboratory before the collision, determine the energy of the
electromagnetic radiation.

Particle Physics
Let's do a little particle physics. Back in the '9os there was a large electron-positron collider at CERN in Geneva, Switzerland, called the "Large electron-positron collider," or LEP for short. (This collider was broken down and rebuilt into an even larger one that runs to this day, called the "Large hadron collider" or LHC.) It was LEP that discovered the W and Z bosons, which mediate weak nuclear processes like the beta decay of free neutrons Anyway, near...

A positron (the electron's antiparticle) has mass 9.11 x 10-31kg and charge q0 = +e = +1.60 x 10-19 C. Suppose a positron moves directly away from an alpha particle, which has charge q = +2e. The alpha particle is stationary. When the positron is 1.00 x 10-10 m from the alpha particle, it is moving directly away from the alpha particle at 3.00 x 106 m/s. (a) What is the positron's speed when the particles are 2.00 x 10-10 m...
