A photon with energy greater than the energy level difference of an atom can indeed be absorbed, but the interaction may not be straightforward. In cases such as Compton scattering, the photon can transfer part of its energy to an electron while retaining some energy for itself. When the wavelength of the photon is not short enough, such as in the case of X-rays, the assumptions regarding binding energy become complex, necessitating a deeper mathematical analysis. Researchers are encouraged to explore the concept of "Compton bound electron" for further insights.
PREREQUISITESPhysicists, researchers in quantum mechanics, and students studying atomic interactions will benefit from this discussion.
Then you cannot make the simplifying assumption that the binding energy is small compared with the photon energy, and the math gets more complicated. That’s why I suggested that you include the word “bound” in the search - that will find some papers that cover this complication.fxdung said:But when the wave leng of photon not short as X-ray then what does it happen?
