Abstract：
Superdeformed bands in ^133,134,137Nd and ¹³¹Ce are found in a systematic study of the high spin,superdeformed light rare earth nuclei.Also the previously reported superdeformed pands in ^135,136Nd and ¹³²Ce are confirmed and further investigated.The experimental search procedure,identification and measurement of the superdeformed bands are described in detail.The systematics in feeding.decay,moment of inertia,relative intensity and structure of the bands are discussed.
