Abstract: (APS)
We report the results of a γ-ray spectroscopic study of Po211 via the Pb208(α,n) reaction at 24-MeV incident energy using a thick target. We observe 26 new γ rays, allowing us to identify 18 states that were not observed in previous γ-ray studies. In total, we observe 45 states below 2.0 MeV. A shell model calculation using the modified Kuo-Herling interaction developed by Warburton and Brown predicts 46 states below 2.0 MeV having spins of 21/2 and below, demonstrating the power of this calculation to provide detailed nuclear structure information on nuclei in the vicinity of Pb208.
