Abstract
The mixing ratio of the main 320-keV, M1 + E2 ground-state γ transition in210Bi has been more precisely quantified, allowing a significant reduction in the uncertainty of measurements of the neutron-capture cross section to the ground state of210Bi from 25% to 0.9%. Accurate values for neutron-capture cross sections to both the ground and long-lived 9-isomeric state at 271 keV in210Bi are of particular importance as Pb-Bi finds increased usage in Accelerator Driven Systems.
