摘要：

We calculate the response functions for octupole vibrations in superdeformed nuclei by means of the RPA using a large configuration space composed of 9 major shells. The strongly collective octupole vibrations with K = 1 and 2 are predicted to appear very low in excitation energy, as well as those with K = 0, if an appreciable amount of pairing correlation is present in superdeformed nuclei. Numerical examples are presented for Hg-192 and Gd144.
