摘要：

Properties of low-lying octupole vibrations (with K = 0, 1, 2 and 3) built on superdeformed rotational bands are investigated by means of the RPA in a uniformly rotating frame. Large configuration space composed of 9 major shells is used. Numerical examples are presented for the superdeformed band in 192Hg as a typical case where appreciable amount of static pairing correlations remains at finite values of the rotational frequency. We obtain strongly collective low-frequency octupole vibrations with K = 0, 1 and 2. It is shown that the properties of the K = 1 octupole vibrations are especially sensitive to the static pairing correlations. The Coriolis-mixings among these soft octupole vibrations are shown to become important when the rotational frequency omega-rot greater-than-or-similar-to 0.2 MeV/HBAR.
