Abstract The levels in the ground band of184Pt are identified up to the member with spin 20 in an in-beam spectroscopy experiment on theγ-rays following the177Hf(12C, 5n)184Pt reaction. In contrast to the situation in the heavier Pt isotopes, where the 10+ to 12+ level spacing is very small, the transition energies in184Pt show a monotonie increase with spin. However, between spin 10+ and 14+ the moment of inertia grows quite rapidly and this appears to be reminiscent of the much more pronounced irregularity encountered in the isotopes of larger mass. This property of the moment of inertia is discussed within a model where twoi 13/2 neutron quasiparticles or twoh 9/2 orh 11/2 proton quasiparticles may be excited and coupled to the rotation of the core.
