Abstract

High-spin states in I-125 were populated using the reaction Se-82(Ca-48, p4n) at a beam energy of 200 MeV and gamma-ray coincidence events were acquired with the Gammasphere spectrometer. The level scheme of I-125 was extended considerably. In particular, maximally aligned states involving all eleven particles outside the Sn-114 core were observed. Comparison with cranked Nilsson-Strutinsky calculations suggests that three of these states are the final I-max states in terminating bands with all spin vectors aligned along a common axis. In two of these, one spin vector is antialigned and points in the opposite direction. In one of the states two spin vectors are antialigned. This is the first observation of a state with such a structure.
