Types of Particles
c. Weak Nuclear Force (between leptons and hedrons)
d. Strong Nuclear Force (between quarks)
Anti-particles: Anti-particles are particles having all properties similar except any one property w.r.to the other particle.
|Properties||For Electron (e-)||For anti-particle of electron (e+)|
|Average Life Span (Same)||l||l|
Pair Production: The phenomena of conversion of energy into matter is called pair production. When energetic photon strikes the heavy nucleus, particles and it's corresponding anti-particles are produced.
