【摘要】 Delayed γ-ray spectroscopy of 185Au was studied at the Argonne Gas-Filled Analyzer.A new isomer at an excitation energy of 1504.2（4） keV with a half-life of 630（80） ns was identified via γ-γ coincidence analysis,decaying via a 294.8（3） keV transition.Based on Weisskopf estimates,the multipolarity of the 295 keV transition is assigned to be E1,M1,E2,or M2.Possible configurations for this new isomer are discussed based on configurationconstrained potential energy surface calculations.更多还原
