Collision cascade

{
  "id": "MLC-T-CHM-002217",
  "term": "Collision cascade",
  "field": "Chemistry",
  "definition": "A series of atomic displacements initiated when an energetic incident particle strikes a target atom, transferring kinetic energy. This primary knock-on atom then displaces other atoms, leading to a cascade of subsequent collisions within the material. The process results in the creation of vacancies, interstitials, and atomic mixing in the near-surface region.",
