Abstract
Excited states in (192)Pt were populated in beta(+)/epsilon decay and studied through off-beam gamma-ray spectroscopy. New coincidence data give no support for several reported low-energy, low-spin states proposed in beta decay and lead to a substantially revised level scheme. The structure of (192)Pt is discussed in terms of both single-space IBA-1 calculations and two-space IBA calculations with configuration mixing. Both models together suggest that it is the perhaps the 0(4)(+) state that corresponds to an intruder excitation, resulting from the excitation of a pair of protons across the Z=82 closed shell.
