PALS – Positron Annihilation Lifetime Spectroscopy
Description: Positron Annihilation Lifetime Spectroscopy (PALS) is a non-destructive analytical technique used to study the behavior of positrons in matter. Positrons are the antimatter counterparts of electrons, and when they encounter electrons in a material, they can annihilate each other, releasing gamma-ray photons. PALS measures the time delay between the creation of positron-electron pairs and …
