Excited states in209Bi

  • F. Demanins

Excited states of209Bi have been studied via the209Bi(n,n′γ) reaction for incident neutron energies from 1510 keV to 4335 keV. From the analysis of the γ-ray spectra a detailed level and decay scheme was constructed up to the excitation energy of 4001.3 keV. Level spins and parities were deduced on the basis of extensive comparison between the measured γ-ray yields and the theoretical predictions based on the statistical model of the compound nucleus. The half-life of the states at 2443.0 keV and 2987.2 keV has been measured to beT1/2(11.3±0.4) ns andT1/2(17.9±0.5) ns, respectively.
