Abstract
A common interpretation of the light Pt isotopes involves the coexistence and mixing with proton intruder states from above the Z = 82 shell gap. An alternative description of the Pt isotopes using a simple, single configuration, the two-parameter interacting boson approximation model Hamiltonian, is discussed. To test these predictions, experiments on 192Pt were performed. New coincidence data found no support for several low-energy, low-spin states previously proposed in β decay. Results from an (α, 2n) experiment identified states of the γ band up to spin 9+. Results of these experiments are discussed in terms of IBA calculations.
