X-rays are produced by high-energy electrons bombarding a target, especially targets that have a high proton number.
- When bombarding electrons penetrate into the target, some electrons travel close to the nucleus due to the attraction of its positive charge
- The course of these electrons would be deflected, and a portion of their kinetic energy would be lost.
- Intermediate energy X-Ray
- Innermost (K shell) electron pushed outside.
- High energy X-Ray
- Outermost electrons are involved.
