Nuclear Structure & Radiation — AQA A-Level Physics
Key Definition
Beta-plus particle — A high-energy positron (the antiparticle of the electron) emitted from the nucleus when a proton converts to a neutron. Notation: ⁰₊₁β. Accompanied by an electron neutrino.
- Emitted by nuclei with too many protons (proton-rich, right of stability line).
- Same mass and penetrating powerThe rate of energy transfer. Measured in watts (W). as beta-minus, but opposite chargeA property of matter that causes it to experience a force in an electromagnetic field. Measured in coulombs (C)..
- Deflected in the opposite direction to beta-minus particles in electric and magnetic fields.
