Final answer:
Compton scatter characteristics include the creation of a recoil electron, interaction with a loosely bound electron, and is applicable at photon energies like 100kV, often resulting in a Compton shift where the scattered X-ray has less energy and a longer wavelength than the incident X-ray photon.
Step-by-step explanation:
Compton scatter, a phenomenon in physics, exhibits several characteristics. The most pertinent to the student's question are recoil electron, interaction with a loosely bound electron, and incident photon energy approximately 100kV. Firstly, a recoil electron is created when the X-ray photon collides with an electron, knocking it out from its atomic shell, which shows that Compton scattering involves the transfer of energy to electrons. Secondly, the interaction with a loosely bound electron is central to the process; it is the outer shell electrons, which are less tightly bound to the nucleus, that are typically involved in Compton scattering. Lastly, while the incident photon energy can vary, 100kV is within the range where Compton scattering can be relevant.
It is important to note that Compton scattering is an inelastic scattering process. The scattered X-ray photon emerges with less energy than the incident photon, often leading to a longer wavelength, a phenomenon known as the Compton shift. The importance of this effect grows with the increase in the energy of the X-ray photons. However, coherent scatter, total transfer of X-ray photon energy, and leakage radiation are not characteristics of Compton scatter and are thus incorrect options for this question.
