Recall that in gamma-ray production, the excited nucleus jumps to a lower level and emits a photon  . In internal conversion, however, an orbital electron is absorbed and ejected along with an X-ray.

After the electron has been emitted, the atom is left with a vacancy in one of the inner electron shells. This hole will be filled with an electron from one of the higher shells and subsequently a characteristic x-ray or Auger electron will be emitted. |  | kolahalb

If the atom happened to have very low atomic number,this would not be possible.

"High atomic number" tells us that  , so even for K-series ^2\gg Ry) , thus it's not optical but X-ray radiation.

2007-11-01 23:10:52 | Why do they (ETS) point out that the atom has a high atomic number? (i.e. "The most probable process after an internal conversion electron is ejected from an atom with a high atomic number is...") Does it have significance?

for low atomic number, it will produce the auger effect and ionize the outside electron. for high atomic number, only thing it can do is emit X rays.

2007-04-02 19:56:01 | When an inner electron is ejected, the atom is left in an excited state. Jumping to a lower energy state one of the outer electrons will drop down to fill the hole. This transition will have its corresponding emitted photon which occurs whenever an electron makes a transition between energy levels in an atom.
From this point just remember:
electron transitions (in atom) = X-ray production
nuclear transitions = Gamma Ray production | |
