A process in nuclear physics where particles are ejected from an atomic nucleus due to high-energy impacts from other particles.
Spallation is used in various scientific experiments to study atomic structures.
Spallation is formed from "spall" (from Middle English *spallen*, meaning to break off or chip) and the suffix "-ation" (meaning the action or process of). The word describes the process of breaking off or chipping away material, often used in the context of nuclear reactions or material science.
Think of 'spall' meaning to break off, and '-ation' indicating a process. This helps you remember that spallation refers to the process of breaking off material.
