Abstract Excited states in ¹²⁰I are investigated utilizing in-beam gamma-ray spectroscopy following the ¹¹⁴Cd(¹¹B,5n) reaction at 70 MeV bombarding energy. A level scheme is constructed with states up to 9 MeV. The levels are classified into several bands and their possible configurations at low spins are discussed briefly. Based on the linking transitions between different bands at higher spins, the excitation energy of the previously reported T_1/2=53 min isomer is ascertained to be 72 keV. Evidence showing the existence of an isomer at an excitation energy of 6.4 MeV is presented.
