Abstract
Neutron-rich rare-earth isotopes were produced in multinucleon transfer reactions between ions and targets. On-line mass separation was used together with β- and γ-ray spectroscopy in these studies. At mass A=169, the heaviest known dysprosium isotope, 39(8) sDy, was identified. It was observed to decay to the ground state of or through a level at 1578 keV. In the A=171 mass chain, a partial decay scheme for 55(3)-s was determined.
