Abstract

The new neutron-rich isotopes ¹⁷⁹Yb and ^181,182Lu were produced in multinucleon transfer reactions by irradiating ^natW/Ta targets with 9 MeV u¹³⁶Xe 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.
