What Does PAL Stand For?
PAL stands for Positron Annihilation Lifetime
PAL, or Positron Annihilation Lifetime, refers to a technique used in materials science and particle physics to study the characteristics of materials at a microscopic level. This method involves the measurement of the time interval between the injection of positrons into a material and their subsequent annihilation with electrons. By analyzing the lifetime of these positrons, researchers can gain insights into the electronic structure, defect levels, and voids within the material, making PAL a valuable tool for investigating the properties of polymers, semiconductors, and nanomaterials.
