To understand how x-rays can be so effective in accelerating the radioactive decay of 178Hf isomeric nuclei it is useful to refer to the energy level diagram.
 
   
There is a very complex band system in which many transitions have been found by nuclear reactions. Very few are excited in the cascades populated by the spontaneous decay of the 31-yr isomer.
