High-spin states in ^{125} I were populated using the reaction ^{82} Se( ^{48} Ca,p4n) at a beam energy of 200 MeV and γ-ray coincidence events were acquired with the Gammasphere spectrometer. The level scheme of ^{125} I was extended considerably. In particular, maximally aligned states involving ...
