Describe pair production
A photon is converted into a particle and its corresponding antiparticle
What is the rest mass of a Gamma ray
Zero
Define specific charge
charge / mass
What happens to the nucleons during beta minus decay?
A neutron changes into a proton
What is a Beta particle?
A high energy electron
What is a nucleon?
A proton or neutron in the nucleus
Why is the strong nuclear force required for nuclei to be stable?
Electrostatic repulsion of the protons in nucleus.
Hint
Answer
What can be transferred by an exchange particle
Force, energy, momentum and charge.
