Translationsspallation
spallation (spă-lay -shŏn) A particularly vigorous type of nuclear reaction in which several particles or nuclei result from a high-speed collision. Spallation occurs when cosmic rays collide at high speed with atomic nuclei, the heavier nuclei breaking up to produce lighter nuclei.spallation[spȯ′lā·shən] (nuclear physics) A nuclear reaction in which the energy of the incident particle is so high that more than two or three particles are ejected from the target nucleus and both its mass number and atomic number are changed. Also known as nuclear spallation; spallation reaction. spallation
