What is another word for spallation?
Pronunciation: [spalˈe͡ɪʃən] (IPA) 
Spallation, a process of particle physics, refers to the fragmentation of a nucleus due to the collision with high-energy particles. Although there are no exact synonyms for spallation, there are alternatives that describe closely related phenomena. For instance, fission is another process in which a nucleus breaks into two or more fragments. Similarly, fragmentation denotes the breakup of a larger object into smaller parts. In addition, ablation is the process of removing material from a surface due to high-energy impacts. Finally, erosion refers to the gradual wearing away of a substance due to external forces, including the impact of particles. Each of these terms describes a different aspect of spallation and can be used in a complementary way to expand our understanding of the underlying physical process.
