CoupledKπ=0+andKπ=0−vibrations inU234

Abstract
The multiphonon method based on Kπ=0+ and Kπ=0− phonons is applied to U234. The anharmonicities obtained for the octupole vibrations are smaller than in the light Ra and Th isotopes and not significantly altered by the coupling with the Kπ=0+ mode. The I=K=0+ and the I=1, K=0− states observed at 1044 and 1237 keV, respectively, cannot be interpreted as two-phonon states.
