Under certain conditions a y photon may be converted into an electron and positron. What is this process called?
|
pair production
|
|
Explain why there is a minimum energy of the y photon for this conversion to take place and what happens when a y photon has slightly more energy than this value.
|
The y photon must have enough energy to be converted to the rest masses of both the electron and the positron. If the y photon has slightly more energy, the electron and positron will have kinetic energy when they're produced and will move away from each other
