Abstract
The location of several single-neutron states in has been identified. The , , and states were found at 853.7, 1560.9, and 2004.6 keV, respectively, by measuring rays in coincidence with delayed neutrons following the decay of . Crucial for obtaining the new data were the improved yields at the mass-separator facility ISOLDE-PSB at CERN. A semiempirically adjusted Woods-Saxon calculation, based on parameters from the Pb region and normalized on the mass data at , reproduces the new single particle energies with good precision.
