Abstract

The new neutron-rich isotopes 179Yb and 181,182Lu were produced in multinucleon transfer reactions by irradiating natW/Ta targets with 9 MeV u 136Xe ions, and identified by mass separation and decay spectroscopy. The measured half-lives of 179Yb, 181Lu and 182Lu are 8.1±0.8, 3.5±0.3 and 2.0±0.2 min, respectively. The properties of the excited states of 181,182Hf are discussed. The possibility of studying neutron-rich nuclei outside the classical fission-product regions is demonstrated. © 1982.
