Characteristic x rays:--
Characteristic X-rays are emitted when outer-shell electron fill a vacancy in the inner shell of an atom, releasing x rays in a pattern that is "characteristic" to each element.
Characteristic x ray production:-
Characteristic X-rays are produced when an element is bombarded with high-energy particles, which can be photons, electrons or ions (such as protons).
→When the incident particle strikes a bound electron (the target electron) in an atom, the target electron is ejected from the inner shell of the atom. After the electron has been ejected, the atom is left with a vacant energy level, also known as a core hole.
→ Outer-shell electrons then fall into the inner shell, emitting quantized photons with an energy level equivalent to the energy difference between the higher and lower states.
E(alpha)=E(L shell) - E(k shell)
Each element has a unique set of energy levels, and thus the transition from higher to lower energy levels produces X-rays with frequencies that are characteristic to each element.
→use of characteristics x rays:-- this type of x rays are used in mammography unit, or soft tissue radiography.
