Abstract
The beta decay of the very-neutron-rich nucleus Y-103 has been studied at the isotope separator IGISOL, allowing for the first time the obse rvation of nonyrast levels in its daughter Zr-103(40)63. The level str ucture is similar to that of its isotones Sr-101 and Mo-105, suggestin g a targe ground-state deformation of beta similar or equal to 0.4. Le vel systematics allows for new level assignments in both Zr-103 and Mo -105.
