Usage: physics; technical
Examples
- When antielectrons collide with electrons, they annihilate each other and release energy.
- The detector identified antielectrons produced in the particle collision experiment.
- Antielectrons are used in positron emission tomography (PET) scans for medical imaging.
- Scientists study antielectrons to understand the asymmetry between matter and antimatter.
- The antielectron has a positive charge equal in magnitude to the electron's negative charge.
