Bremsstrahlung is the process in which an accelerated electron radiates and loses energy in the form of a photon(production of continuous X-rays). In photoelectric effect, an atom absorbs a photon and an electron from one of the shells is ejected. So, is it reasonable to regard X-ray production and photoelectric effect as inverse processes? On a similar note, in the process of internal conversion, an excited nuclear state comes down to ground state without the emission of a gamma ray(photon). The energy [itex]\Delta E[/itex] involved in this nuclear transition gets transferred directly to the bound electron of the atom and such an electron gets knocked out of the atom. Does this process(internal conversion) share an analogy with photo-electric effect?
