Hello, ARM stands for "atomic relaxation model". And yes, it is the simulation of whatever rearrangement mechanism -X-ray (PIXE), fluorescence, Auger electron- that happens after radioactive decay, electronic capture, etc. Then I can't answer the level of details with which it is done, the electromagnetic physics specialists of Geant4 will certainly do.
