Spectroscopy of Ir-Pt-Au nuclei near stability by complete and incomplete fusion reactions.

High-spin states of 194,195Au, 195Pt and 193Ir have been studied using an in-beam γ-ray spectroscopic technique following the reaction of 7Li on an 192Os target at 44 MeV. Several bands in these nuclei have been identified and extended up to high-spin states. The α and t emission channels leading to 193Ir and 195Pt, respectively, are strongly enhanced which may be explained by incomplete fusion reaction; the t and α fragments from the break-up of weakly bound 7Li nucleus fusion with 192Os target.
