The level structure of {sup 132,134}Ba was investigated in ({ital p},{ital t}) transfer reactions. High resolution spectra (7{endash}8 keV full width at half maximum) with targets from a mass separator allow us to resolve levels up to 4.0 MeV. New 0{sup +} states are identified. The monopole transfer strength shows distributions similar to those observed for {sup 194,196}Pt. 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. {copyright} {ital 1996 The American Physical Society.}
