摘要: The properties of high spin states in 209Po have been investigated using the 204Hg (9Be,4n) reaction at a bombarding energy 62 MeV. Decay for up to an excitation 8392 keV and spins J=(47/2) deduced. mean life level 4266 was determined as 172(5) ns limit <15 that 5504 keV. scheme is compared with predictions multi-particle shell model calculations. lowest core excited state confirmed be 31/2− Another lies 5356 keV, while above 5.5 MeV yrast line exclusively composed such excitations.
