What is Positron – Properties

The antiparticle of the electron is called the positron; it is identical to the electron except that it carries electric and other charges of the contrary sign. When an electron collides with a positron, both particles tin can be totally annihilated, producing gamma ray photons.

The positrons are positively charged (+1e), most massless particles. Their rest mass equal to 9.109 × 10−31 kg (510.998 keV/c

ii
) (approximately 1/1836 that of the proton).

Like all uncomplicated particles, electrons exhibit properties of both particles and waves: they can collide with other particles and tin exist diffracted similar lite.  The original thought for antiparticles came from a
relativistic moving ridge equation
developed in 1928 by the English scientist
P. A. M. Dirac
(1902-1984). He realised that his relativistic version of the Schrödinger wave equation for electrons predicted the possibility of antielectrons. These were discovered by Paul Dirac and Carl D. Anderson in 1932 and named positrons. They studied cosmic-ray collisions via a cloud chamber – a particle detector in which moving electrons (or positrons) leave behind trails equally they move through the gas. Positron paths in a cloud sleeping accommodation trace the aforementioned helical path as an electron but rotate in the reverse direction with respect to the magnetic field direction due to their having the same magnitude of accuse-to-mass ratio but with opposite charge and, therefore, contrary signed charge-to-mass ratios. Although Dirac did not himself apply the term
antimatter, its use follows on naturally enough from antielectrons, antiprotons, etc.
