What are the major effects encountered by an electron traversing matter? more than one answer

multiple Coulomb scattering

bremsstrahlung

Compton scattering

conversion into electron-positron pairs

annihilation

photoelectric effect

energy loss by excitation and ionisation

Expert Solution

The correct answers are:

multiple Coulomb scattering

bremsstrahlung

energy loss by excitation and ionisation

Coulomb scattering is the scattering of electron due to the coulomb force from the positive nuclei. When an electron traverses matter, it encounters many positively charged nuclei. Therefore it can undergo multiple Coulomb scattering.

Bremsstrahlung is the electromagnetic radiation produced by deceleration of a charged particle when deflected by another charged particle. An electron traversing a matter is deflected by positive nuclei hence it can emit bremsstrahlung radiation.

The electron can interact with an atom of the matter and excite it to a higher energy level by losing some energy. The electron can also collide with the atoms of the matter and knock off some electrons from it. This is called ionisation.
