Abstract

The β decay of the very-neutron-rich nucleus ${}^{103}Y$ has been studied at the isotope separator IGISOL, allowing for the first time the observation of nonyrast levels in its daughter ${}_{40}^{103}{Zr}_{63}$ . The level structure is similar to that of its isotones ${}^{101}{Sr}$ and ${}^{105}{Mo}$ , suggesting a large ground-state deformation of β≃ 0.4. Level systematics allows for new level assignments in both ${}^{103}{Zr}$ and ${}^{105}{Mo}$ . © 1996 The American Physical Society.
