What is the difference between ionization and photoelectric processes in terms of their interaction with matter?

Ionization is the process of removing an electron from an atom or molecule, creating an ion. This process can occur through collisions with high-energy particles. On the other hand, the photoelectric effect involves the ejection of an electron from a material when it absorbs a photon of sufficient energy. In terms of their interaction with matter, ionization can occur through various mechanisms, while the photoelectric effect specifically involves the absorption of photons to release electrons.
