Abstract

The heaviest known erbium isotope, 3.3(2) min.174Er, has been identified using on- line isotope separation and by ß and γ- ray spectroscopy. Twelve γ rays were placed in a preliminary decay scheme. The mass of the new isotope was established by the separator and the Z was deduced from Tm K x ray coincident ß and γ rays. In addition, the heaviest known isotope of holmium171Ho was observed with a half-life of 49(5) s.
