Abstract

Comprehensive evidences of the SU(3) limit in the spdf interacting boson model, a dynamical symmetry describing octupole vibration in rotational nucleus, are found in the spectrum, E2 and E1 transition rates, and relative intensities in 158Gd. This gives a good example of rotational nucleus with octupole vibration in rare-earth region.
