Abstract
The level structure of was investigated in (p,t) transfer reactions. High resolution spectra (7–8 keV full width at half maximum) with targets from a mass separator allow us to resolve levels up to 4.0 MeV. New states are identified. The monopole transfer strength shows distributions similar to those observed for . This is consistent with the O(6) limit of the interacting boson approximation (IBA-1) model, without ruling out other, more microscopically based interpretations for the low-lying structure of these nuclei. We also compare with the IBA-2 model and geometrical model calculations. © 1996 The American Physical Society.
