The targetatom or ion may be excited to infinite bound states, auto-ionizing states and adjoint continuum states which can be treated in an unified manner by Multichannel Quantum Defect Theory.
Within activity: object, activity: target, and atom: author elements are one or more activity: object-type elements that contain an atom URI defining the parent object.
Various metal or metal the material composing a target is collide with by electrified ion is brought about the metal atom becoming the free particle deposition surface in mylar above.
