They destroy each other and radiation is released.

What is positron emission?

It is a beta plus particle and it is an antiparticle so it carries a positive charged neutrino is also unchanged is emitted.

2 of 17

what was the theory about rest energy being directly linked with rest mass?

E = mc^2

3 of 17

What was Dirac's Theory?.

- Annihilates the particle and itself if they meet, converting their total mass into photons.
- Has exactly the same rest mass
- Exactly opposite charge to the particle if it has a charge.

How do you find the energy from rest mass energy and kinetic energy.

E = mc^2+ke

What is pair production?

It is when a photon produces an anti particle and a particle when interacting with a nucleus.

6 of 17

What is Annihilation?

It is when an anti particle and a particle meets each other and annihilates each other producing 2 photons.

What is 1 MeV (Million electron volts) = to?

1.60 x 10^-13

8 of 17

What is the equation of minimum of each photon produced?

hf(min) = E>0

9 of 17

What is the equation of each photon needed to make 2 particles?

hfmin = 2E>0

10 of 17

Why sometimes a photon cant create an antiproton and proton pair?

the photon doesn't have enough total energy to make the minimum energy for proton.
