Abstract

The multiphonon method is applied to heavy nuclei using the collective

K = 0^{-}

octupole state as the building phonon. A good description of the

K = 0^{-}

band is possible even at low energy

E

where the random-phase approximation fails. It also becomes clear why one has not observed

K = 0^{+}

states with an energy of the order of

2 E

.
