Abstract
The structure of the neutron-rich bismuth isotope has been studied for the first time. The fragmentation of a primary beam at the FRS-RISING setup at GSI was exploited to perform -decay spectroscopy, since isomeric states were expected in this nucleus. Gamma rays following the decay of a isomer were observed, allowing one to establish the low-lying structure of . The level energies and the reduced electric quadrupole transition probability from the isomeric state are compared to large-scale shell-model calculations.
