1998年1月1日 · Note: Animation of positron-electron annihilation. Animator: Edgar Russell (NASA). Scientist: David Leisawitz (NASA/GSFC).

A simple animation showing an Electron–positron annihilation, when an electron e− and a positron e+ collide. At low energies, the result of the collision is the annihilation of the electron...

The positron or antielectron is the particle with an electric charge of +1e, a spin of 1/2 (the same as the electron), and the same mass as an electron. It is the antiparticle (antimatter counterpart) of the electron. When a positron collides with an electron, annihilation occurs.

Because a positron is the anti-twin of an electron, they annihilate when they find each other, as seen in the GIF below. All their mass is converted into energy, in the form of two photons, seen in pink. They do not annihilate immediately because it takes the particles a while to find each other.

2015年3月29日 · I read that, in an electron-positron annihilation, at least 2 photons are produced, because of the law of conservation of momentum. my question is: in what direction are those photons released? and how accurate is this animation?

Proton-Proton Animation. Shows an animated diagram of the proton-proton chain reaction, which is the dominant fusion reaction in the sun's core.

In this animation you will learn how electron and positron collide with other and then convert into photon energy

Positron An electron is a small spinning current loop holding a larger magnetic loop with defined north and south poles. Although confined to a very small area, about 2.8 femtometers (Lorentz radius = 2.8×10⁻¹⁵ meters), with the larger magnetic loop fully covering the smaller current loop.

2018年10月10日 · Electrons and positrons can be accelerated near the edge of the current sheet. This movie presents a tour from the inertial frame and spinning up to the co-rotating frame around the simulation magnetic field including motion of the high-energy electrons and positrons.
