Positron
Dit artikel is gesjreve (of begós) in 't Sint-Joasters. Laes hie wie v'r mit de versjillende saorte Limburgs ómgaon.
E positron is 't antideilke van 'n elektron. 't Haet dezelvendje massa, mer 'n taengegestèldje lajing en wuèrtj aangegaeve es e+.
Positrone kómme vrie bie 't radioaktief verval van sómmige isotoape, wie 23Na. In principe zint ze juus wie elektrone stabiel deiles, meh wen e positron en 'n elektron op einanger boetsje annihilere ze einanger. Dit wil zègke det alle massa wuèrtj ómgezatte in innerzjie (fotone). Dit neump me gammastraoling:
- e+ + e- => γ + γ
De twieë gammaquante zólle in taengeneuvergestèldje richting vanne plaats van verinnewering ewegbewaege. De gammastraoling kan (geliektiejig) waere gemaete.
