Antimatter and Matter
Paul Dirac -->1928
In cloud chamber, a particle with an identical mass of electron was seen. Particle was slowed in lead and decreasing radius showed it was travelling <--. There was a down magnetic field showed us it was positive . This was POSITRON
Properties of antimatter:
:check: Mass of particle = Mass of antiparticle
:check: Charge of antiparticle = Opposite charge of particle
:check: When particles and antiparticles combine, the pairs annihilate one another producing a lot of energy
:check: Spins in opposite direction
:check: Not found in normal matter but arise in:
1) High energy collisions
2) Interactions with cosmic rays
3) Radioactive decay
