High-spin states in the neutron-deficient nuclide I-111 have been populated
with the fusion reaction Ni-58 + Ni-58 at a beam energy of 210 MeV, in an
experiment performed at the Tandem Accelerator of the Laboratori Nazionali
di Legnaro. The gamma spectrometer GASP was used in time coincidence with t
he ISIS Si-ball and the CAMEL recoil mass spectrometer for the positive ide
ntification of the nuclide. Gamma transitions and structure details previou
sly attributed to I-111 by Other authors are only partially confirmed. The
obtained level scheme includes new rotational bands and a new low lying str
ucture which suggests the presence of octupole correlations at predicted ro
tational frequency values.
