High spin states with angular momentum up to 21[h bar] in [sup 84]Y have been established for the first time through the discrete-line [gamma]-ray spectroscopy using the [sup 59]Co([sup 28]Si,2[ital pn])[sup 84]Y reaction at 98 MeV. The experimental level scheme exhibits rotational characteristics with a large signature splitting and also signature inversion at [ital I]=11[h bar]. Theoretical calculations using the particle-rotor model with axial symmetry provide a good description of the observed phenomena.
