Question

(A) Characteristic $X$-rays are produced due to electronic transitions within the target atom. When a high-energy incident electron strikes the target

Vedclass · Accepted Answer

An electron is knocked out from an inner shell of the target atom,and an electron from an outer shell fills the vacancy.

Vedclass · Answer

(A) Characteristic $X$-rays are produced due to electronic transitions within the target atom. When a high-energy incident electron strikes the target,it knocks out an electron from an inner shell (e.g.,$K$-shell). This creates a vacancy in that shell. To stabilize the atom,an electron from a higher energy shell (e.g.,$L$ or $M$ shell) drops down to fill this vacancy. The difference in energy between these two shells is released in the form of a photon,which corresponds to the characteristic $X$-ray emission.
