Abstract
Lutetium and ytterbium isotopes with masses A=159,158 have been produced by proton induced spallation reaction, and investigated by on-line mass separation and subsequent decay spectroscopy. A new isotope159Lu (T1/2=12.3±1 s) has been identified, and newγ-ray data have been obtained for the decay of158Lu and159, 158Yb.
