Abstract.

We study properties of the excitation modes built on the superdeformed states in sulfur isotopes close to the neutron drip line by means of the RPA based on the deformed Woods-Saxon potential in the coordinate mesh representation. We find that the low-lying state created by the excitation of a single neutron from a loosely bound low-Ω state to a high-Ω resonance state acquires an extremely strong octupole transition strength due to the spatially very extended structure of the particle-hole wave functions.
