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
