A study of collective octupole states in barium in the interacting boson model

We analyze low-lying collective negative parity states in 140–148Ba in terms of the interacting spdf boson model. We point out the crucial role played by p bosons in describing E1 transitions. We discuss the rather unusual properties of the nucleus 146Ba.
